Cosmo in Southampton

The best all you can eat I've ever had! There is a sea of options from different cuisines all over the world: Japanese, English, Italian, Chinese, Vietnamese, Indian, French. They have a grill with a chef where you can go and ask for stuff, depending on the day, and also a griddle with another chef cooking proteins. Everything is fresh, and tasty, cooked carefully and with attention to detail. The price is extremely reasonable. I am not from Southampton, but I wish I was just for this restaurant!

Brilliant customer service and amazing food 👌

A busy "all u can eat" with an excellent selection of grub from Salads, Roast dinners, pizza, Japanese & Chineese style, Indian and a hotplate where fish or meat or both is cooked while you wait. Beer not overpriced either.

Good selection of tasty food with friendly and hard working staff.

I appreciate that on Saturday evening a lot of dining venues will be busy and the Saturday evening I went was no exception having a 30 minute wait for a table. But to then be told that once you have a table you have a one hour slot to eat before you have to leave just put a downer on eating there, to the point where I didn't, hence the three star review.

Cosmo has really nice food and you get to experience different flavours from around the world. Wish they had some African dishes though. Overally it was great.

Came here for Mothers Day with the family. Great selection of dishes, accommodating for everyone’s taste. Good service, attentive from our waitress.

Great food, lot's of choice, eat as much as you like.

It was the best buffet ever! It had so many yummy and fresh food/deserts the drinks came with straws and big cups there was so much yummy options

Probably the best meal so far this year. I visited at 17:30 on a Saturday and was warned I may need to wait an hour. After 30 mins, a pager flashed and I was given a table. Well organised. Almost everything I had was tasty, and better than 5 star hotel buffets, in my experience. Better also than my first visit to a Cosmo in Norwich.

Just had an amazing meal here! The food was absolutely spot on—everything from the Chicken Meat Balls to the Sweet & Sour Chicken hit the mark. The atmosphere was lively, and the service was on point, making for a brilliant evening. I can't think of a single thing that could be improved, so keep up the good work! Definitely coming back for more deliciousness.

Excellent place for a family gathering with plenty food and love

Never been before so wasn't sure what to expect, but enjoyed it. All the food was really tasty and there's plenty of it to choose from, although more so on the Asian style/theme dishes as opposed to others. Great if you're not sure what you fancy and are really hungry, although not the cheapest place to visit for dinner. Service was very good and staff were all very polite and helpful so would come again 👍

Gets a little loud with the amount of people and a lot of people shoving in the que but dont let that put you off. The place is always so clean and tidy. Staff have always been polite and helpful. Food selection is incredible and always so fresh and tasteful. Every item has its own tongs/spoons so no cross contamination. Every item has its allergens right infront so you dont have to ask for them. Little more pricey than where we normaly go for date night BUT its worth it.

I would give no star if it was allowed!!!! Appsolutely fuming. I pre booked a table for two at 7:30pm as it was my Fiancée birthday and when we arrived we got told it was a half hour wait. We was not impressed as other members of the public who haven't booked a table got priority over us and others that had booked tables. There poor excuse was they messed up there booking arrangements blaming it of half term. This is a very poor excuse and they didn't seem to care about it. We ended up having our meal at Casas Brasil and had much better service there and got seated within 5 minutes unlike you guys. You are a disgrace and you need a better booking system and people who have booked in advance get priority, this is discrimination in my eyes and I will be reporting this to trading standards too!!!!

Waiting time was bit long so I'll recommend a booking. But all good. Food is great. Good value for money too

The food excellent the view from the windows is Amazing

This was my first visit to Kosmos. My husband and Colleagues went there for their Christmas meal I finally enjoyed my first visit. Will definitely be back once a month probably more. I also want to try the lunchtime menu so we’ll be back next week to try Would highly recommend Cosmo to anyone looking forward to my return

"With its warm decor and friendly service, Cosmos in Southampton is a restaurant I’d highly recommend. The incredible variety of food caters to all palates, and they certainly don’t skimp on flavor. It’s a great opportunity to try dishes you’ve never had before—if something’s not to your taste, simply move on to the next option, and your plate will be cleared by the time you return. The value for money is excellent, with an abundance of choices and authentic flavors that make every visit worthwhile."

I visited recently and had an absolute blast! The food was top-notch; I loved the lamb Rogan Josh and those perfectly cooked squid. The atmosphere was buzzing, and the service was spot on, making it a total treat. Just a thought—adding some veggies and noodles to the teppanyaki station would be awesome! Overall, I can't wait to come back in a couple of months!

We normally go very often sadly yesterday we decided that is the last time and we would rather to pay for an expensive restaurant and have a a good service . After not even an hour the waiter were going to the table an ask my husband if he was finish while he was eating , after a lady came to our table and told us that we were just allow to be in the restaurant 1 hour from the moment we stepped in we weren’t there not even the full hour .

I love the environment, and all the foods. I love the freshely cooked prawn and squid cooked by chef Prashant. Lovely dine out .

This is an average buffet - exactly what you'd expect from a chain like this. Good variety of food and the drinks are reasonable.

Great range of quality food which we all enjoyed. Something for everything. And, although it's expensive, we definitely got our money's worth. The experience is like a buffet in a 4 star hotel, so there's a bit of a scramble when busy.

A wonderful restaurant! A huge variety of dishes, all very delicious. The staff are very friendly, and my son, who visited for the first time yesterday, said that Cosmo restaurant is the eighth wonder of the world. We will definitely be back!

First time here, we went on a Friday lunch time, we booked but it was very busy. Can't complain about the food, not loads of vegetarian options but ok. Just daal and cauliflower curry in Asian section. Its much smaller than the Croydon one. Parking a bit confusing if you've never been to West quay. Cosmo is on the 7th floor and head south along the walkway. They add a service charge onto your bill btw. Was £90 for 4 adults. No drinks. Would go again if in the area. Staff very polite and attentive. 🙂

Great food and a massive selection, something for everyone, food was hot and tasty 😋 service was good and fast , recommended

Took my 2 kids aged 5 and 9 they absolutely loved having the ability to pick there own foods!

Good place, tasty food and large selection of dishes. Happy to recommend.

These buffet restaurants are dotted around England and provide food from different countries around the world. Trying different foods will get your taste buds going, you know you are getting your money’s worth when you’re eating from one plate to the next. I’m more into deserts and I found this exceptional. Being popular, this restaurant is very busy and staff are extremely helpful. Overall it’s worth a visit.

Gran variedad de comida. Todos lo disfrutaron. El personal era amable. Buen precio como puede tener tanto como desee de diferentes alimentos.

Bring some earplugs, the place is very loud, food is mediocre, not much taste to any of it. Mass produced with cheap ingredients.

I had a great meal recently and really loved the atmosphere—so lively and clean! The service was spot on, and I found the food to be fantastic, especially the Beef in Black Bean Sauce and the Sweet & Sour Chicken. Just a couple of suggestions, though: it'd be nice to see cheese and biscuits on the menu and maybe hot drinks served as bottomless. Overall, I left feeling satisfied and would happily return!

Absolutely terrible. We came here because we had been to JRC a couple of years ago and it was brilliant, but it has sadly closed down since, and we were told that Cosmo was similar, so we came here, but we soon regretted it! There are a number of reasons why it was so awful; - The staff were rude and dismissive - It was overcrowded, probably because they don’t want to turn away bookings (aka money) - Everything was very disorderly and unorganised and chaotic - The food was uncovered and unhygienic, think how many people could have breathed, coughed, sneezed, etc over what you have to eat! - The ingredients of the food seemed really cheap and substandard, the chicken “neggets” which was what it seemed to say on the sign for some unknown reason tasted like cardboard, the ones from Burger King are nicer! It all tasted and looked like cheap, bad quality wholesale food. - The refill soft drinks options were awful, the only branded drinks were Coca Cola, the rest were all cheap brands. - We asked for two J2Os, and when we got back to the table, there were two orange Fruit Shoots there! - Most of all, it was ridiculously expensive. We had a terrible experience, we hardly got much food because it was all so awful, and it came to over £100 for 4 people. I wouldn’t consider this bad if we had enjoyed the food and if it had been of a high quality, but it was absolutely substandard! I’d have rather gone anywhere else, I’d rather spend £100 at McDonald’s than this, I’d probably get better value for money! (And that’s saying something, because I hate McDonald’s and always have!) If you have any sense, just don’t come here!

Good price good food, go hungry and stuff your face.

I had an amazing time here! The food was delicious and the quality was top-notch, with plenty of variety to choose from. Everything was replenished quickly, so we never had to wait for more hot meals. The atmosphere and service were spot on, but I did have a bit of an issue with the drinks running out. Overall, it's a great spot, and I'll definitely be back!

Stay away from here when you're just with the 2 of you. No atmosphere at all. Very noisy with screaming and running kids. Some of the food is ok but that's pushing it. Better go to a proper restaurant. Probably cheaper and definitely more enjoyable and better atmosphere.

Food is always good. Large selection to choose from. Prices are roughly £22 a person plus the refillable drink cost. They do offer birthday meals for free if you bring four people to eat. Would definitely recommend going to their website to reserve a table depending on the day and time you go, because they do get really busy. Reservation is not demanded but recommended to reiterate. They do have a bar available as well and a decent size dessert bar area.

Food was good but service not as great asked for water and ice and lemon got water and was told to ho to sushi deck if wanted lemon for my water got no ice. My point is this is a allergy concern for staff to say that to someone who can't have fish. It takes 2 mins to get lemon from the bar. I wouldn't have minded paying the service charge if service was better. Just something for you to think about going forward. But thanks for the lovely food.

Good evening. Came for the first time, without a reservation. We were told that for the amount of 21 pounds we could only stay for 1 hour (we arrived at 17.00). We wanted to book right away, we went to the website, and there, if you book, you can get back to this restaurant at 19.00 and you can only stay in it for 1.5 hours. We left disappointed. Why such inconvenient time limits?

Really nice atmosphere very tasty indian food,nice and hot,helpful staff indian section beautiful and tasty 😋 😀

What can I say? It's an all you can eat buffet. I think it's overpriced, but the food quality is good. It's not a posh restaurant and be prepared for all sorts of people moving around all the time coming and going for each visit to the buffet. £47.36 for 2 to eat & £9.68 for 2 drinks on a sat afternoon. Anyway, we enjoyed it because it was something different and we liked the food choices. Bit noisy, and we didn't like being sat close to the buffet. Prob better for us if we had a window seat to enjoy the view as we had not been here before. We will return, though, so it wasn't that bad. ****Update**** We did return, only 3 of us this time. Nothing changed, and we still were not fortunate enough to be given a window seat. Boohoo. I did (however) discover the steak & fresh prawn grill. Wow, I really enjoyed that. Just ask for what you want, and they cook it right in front of you. Nice. We popped up for a netball tournament and drove the extra 35 miles just to eat here. Bit of a treat for my daughter. Still pricey, parking/traffic was a nightmare, but we're rarely in this neck of the country, so what the heck.

I had the best experience out of any restaurants in wetquay here. The food was good and the customer service was however on person stood out. The teenage girl with black hair around 5 foot 5 was very nice to me and was very patient before taking my plates in a quick and orderly manner. Seriously this girl deserves a pay rise I’ve never had such good customer service here before. :)

A decent place of food when there’s enough room to move around. Lately the restaurant owner have been a bit too greedy and filling any small space not leaving space to move around between tables. NO SPACE TO MOVE BETWEEN TABLES TO EVEN REACH THE BUFFET!!

Food was amazing considering it was a buffet! Just a little noisy and crowded

Busy due to Christmas but staff member on the welcome desk was very rude but the others were great

So I have been to a few all you can eats. These have all been a certain type of food. Here there is so much choice. Something for everyone. It has great to try new foods also. Pudding area was great. Lots of different things. Also winner with chocolate fountain. Kids loved it. Staff where nice. Only issue was took almost 10 minutes to get plates. Furniture was very nice and was clean even though it was super busy.

I’ve never sat in a restaurant and been given an evil look quote like this cosmo,

It has the atmosphere you would expect at an international buffet. Buzzing and not very quiet. But that’s part of the fun isn’t it? 😌 The food was actually very nice and I was happy with the choices as well. The desserts could have been a bit better I thought though. The staff was very kind and helpful. The ambiance and the interior is attractive and the restaurant is suitable for any kind of a group such as family or friends or colleagues. It is a popular place for birthday celebrations and other kinds of celebrations as well. They had Indian, Chinese, Japanese, Mediterranean and a few other cuisines. I’d recommend this to anyone! 4 stars since I thought the table and the chairs could have been a bit more thoroughly cleaned after the previous customers.

Been on the phone waiting for someone to pick up so I can book for over 1.5 hours. This is super bad service.

All you can eat what else needs to be said..

Went on a Saturday night, had a great time. Enjoyed the food and the service. Kids running around screaming was a bit much though, and some other customers who clearly have no manners or common sense, but none of this is on the restaurant. I will be coming back

El servicio era de clase mundial, personal amable. La comida era de primera categoría relación calidad-precio. Todo el mundo estaba alojado y el desierto era exquisito

Llegó a las 8. 33 pm con gemelos en buggy para que le digan que cierra a las 9 . 30 pm, así que no pudimos entrar. El personal dijo que no había entrada después de las 9 , yo señalé que eran las 8 . 33

Worst customer service ever all they care about is money bad food and getting you out don't phone unless you want to wait 20mins even when you are paying over£200 I will never go back there

The service was absolutely horrible by a particular member of staff. When we went to the reception the young lady had a horrible attitude idk what was wrong with her… she didn’t have a smile on her face or even apologise for the inconvenience that we faced. food and atmosphere was good but JEEZ they need to get better customer service.

Superb choice of food as usual. Wish they would open every weekday at lunchtime like they did pre Covid, when we visited almost on a weekly basis.

Noisy, expensive poor quality food and that's before the compulsory service charge. Don't waste your money

Had the worst experience ever from a very rude and racist manager who I zvedu condescending and abrupt to black customers ! This is not the firsts time she has behaved like this and all black families who wanted to dine there were left standing in the lobby and spoken down to like they were nothing some even left. This has gone on for some time and Cosmo Soiuthampton need to deal with this now !! she has been very rude to customers for a long time now

We came for a 60th anniversary today and the lady that was looking after our table (Nicole) was so attentive, she went above and beyond in looking after us and is a real credit to your team. Thank you so much. Food was lovely and lots of variety.

Great place to eat. Lots of choice and good value for money.

Didn't like it myself food very basic and bland Much better spending money at a non outlet food chain

have no photos of proof but i went today with my girlfriend and we had a very nice chinese dish to start with and it was amazing the honey chicken wings was my favourite but then my girlfriend went to go get her second dish a roast dinner chose the gammon as its one of her favourite meats to have with a roast and she came back sat down went to eat the meat and i went no stop do not eat it luckily i had saw it before she ate it but there was mold on the side of the gammon i then told the staff and the manager came over crapping him self thinking of every excuse possible but then decided to give me 50% off now why would you do that if you was so certain it wasn’t mold he had reapetedly told me it was burn marks from the over but that was impossible as if that was the case with a kinfe you should be able to scrape it off but that wasn’t the case it was 110% mold it’s very silly of me because i should of took photos of proof but as i was so amgry i went up and spoke to the staff straight away. please be careful anyone eating in there check your food before you eat it im not saying it’s a bad place but just be careful

Indian food is good down very badly, it used to be good now the quality of the food is bad maybe the chef who is cooking don’t know how to cook Indian food. Rest all other food was good

Amazing variety of food and it was yummy! Definitely worth the price! You can even do bottomless soda! Also the staff is friendly and helpful!

Cosmo, absolute great! Me and my friend went there; our first holiday on our own. We booked our meal in advance and we are glad we did as it was fully booked, and now i see why! The staff were friendly, and happy to help, even with a high demand of customers. The food was amazing and a good variety of food from around the world. I try many new foods and turned out i loved most of them. Good variety for everyone including kids, as had some basic food too, and good desserts such as a chocolate fountain. Will definitely be returning when we go back to southampton. Highly Recommend

went on a sunday and it was busy as. we made a reservation for a birthday which they said they would bring a cake but never did. relatively good options but ive been to bigger and better buffets. not rhetorical best desert options but hey. clean place and nice workers

Firstly the food is outstanding, freshly cooked and staff putting fresh out every few minutes. The atmosphere in the restaurant is very good everyone enjoying themselves at the buffet. The only down side that could be addressed is you are meant to get 1hr and 45minutes seating but email states this might be reduced to 1hr and 30 minutes which is fine but when we came last night 1hr and 5 minutes into our seating a waiter came up to our table and said we need the table back which isn’t right. This made us feel uneasy and we paid and left. We will definitely come back though

Eat as much as you like but only in… 1h. Ridiculous. Avoid

My partner & myself dinned last night and we were so disappointed with how we were rushed in the end. The lady in charge came to the table with the bill and card machine, she demanded us to pay straight away as if we weren’t trusted that we would make the payment. We’ve dinned on numerous occasions where the service was excellent, but our last visit wasn’t a great experience.

Buffet good variety . Food taste good . Amazing service for a buffet , all staff really friendly . Highly recommend if you can’t decide what to eat , you can have it all 👍👍

Saturday is quote busy so I'd avoid that if you can. Service was good, dirty plate collection came a fair amount so everything was kept clean and tidy. Food was good, Indian curries seemed subpar but other than that, no complaints. Guinness wasn't the best but again, with the amount on offer, it was okay but I wish there was a wider draught selection. Overall very good, would come again :)

TBH I was wary about going to this type of restaurant as not normally the type we visit. However, two teenagers liked look of it. And I was surprisingly impressed, food was lovely, tasty and well cooked. A great range to choose from for all ages. Liked that could choose from buffet but also had choice of cooking several dishes in front you while waited. I noticed that they were checking temperature of the food which impressed me. We visited on early Friday evening, it was busy but no big queues for the food and dishes were all being replaced and not out of any. The service was efficient and staff soon cleared away any plates after each visit to the buffet. Atmosphere was great for an evening. All in all a good place to visit and great value for money. I definitely over ate :)

Good restaurant. Plenty of good food. But there was one unhappy thing. I'm a young lady and the teppanyaki staff asked me if I wanted one slice of beef or two but the two tall men next to me were both given two slices straight away without asking - I felt unfair and uncomfortable.

The building itself is a great idea 😁. The place is loaded with lots of eateries. A good choice for food.

Great food and atmosphere. Very clean and everything was hot. Very polite staff.

A nice place to have buffet in Southampton. My usual go to place for some celebration

Every time we’re in Southampton we have to go to Cosmo! It’s lovely, clean, the staff are so friendly and the food choice and quality is incredible!

A very good option when your party had different dietary habits. Options varies from Asian to European including many options for children. A good options for a quick dinning.

It's ok if you are hungry and fancy different foods great for kids, I agree with most of the review's food quality is not the best but it is a buffet so bit of a trade-off volume over quality but you will find something you like. I would give the curry's at the back a miss not nice but overall good service and clean worth a visit.

First time here. Really surprised. Very well organised, very clean, great food that was well presented and tasted so good. A wide selection of food and then......... the sweet selection!! mmmmmmm. My only dissapointment was a service charge on my bill. I was not given the option of this. Gave my table number at the till and the card machine was presented to me with the total including two drinks. Only as i walked out did I see a 'Discretionary 3% service charge added to the bill' A little rude when we served ourselves and this was added automatically. I didnt realise if it was your Birthday you eat for free. We were there for my Wifes Birthday.

Excellent food, lots of choices, service great, good value for money. We were a party of seven, celebrating a double birthday, and would certainly go again.

Awesome for something different and a chance to buy different meals . Been twice now

The cost now being north of £20 makes it hard to feel like it's worth going here over going elsewhere for a meal.

Brill place to visit, if you like all kinds of food! There is something for everyone…

Very good food with a lot of options, staff friendly and accommodating

Food-wise it was fine but the hygiene of the bowls/plates etc was not. The black bowls in particular all had grease in and other little unknown bits which was very unpleasant to have to eat out of as they seemed to not be washed properly, same with the other things like plates and glasses.

Cosmo is relaxing, offering a wonderful atmosphere.

Asked for alcohol free beer, got one with 4.5% alcohol.

We have been many times, However the food quality is very bad and today I in the egg and sweetcorn soup 🍲 Was very salty, also the curry's too There was no egg fried rice Till we asked , the staff was rude in the sea food section, Not worthy at all not recommending to anyone Didn’t enjoy at all! Very disappointed

I liked the food, but I wish there would be more variety of international food. It's mostly British, Indian, Pizzas, Asia

Eat all you can buffet sounds great as long as the food is great too. The price of over £20 per adult for the quality of food you are getting is way too much. Most things don't surprise you with taste and many dishes lack taste at all. Pizza taste worse than frozen pizza from supermarket. Spaghetti is very watery and you can barely find any meat in there, burgers taste worse than McD. Curry and other stuff don't taste like they should and leave you with a lot of disappointment. I think The chocolate fountain is the best food there. And you have to pay extra for a fizzy drink like diet coke and coke zero but no regular Coke. There is also some lemon and orange drink but that is as good as coke zero and diet. There are plenty of people trying to get food but there is not much space between the food stalls so you have to almost fight for food. Obviously, kids love this place because of the dessert section but even desserts can't make up for very poor quality main dishes...

Food wasn't amazing some pink tinges to chicken, duck looked like minced pigeon carvery wasn't a carvery overall food wasn't amazing but the staff were extremely brilliant always on hand to take drink orders or to remove finished plates staff were amazing but the food did let it down.

The best thing you can eat anythings free on your birthday as a treat. 💕👍

It is recommended to make an appointment in advance. There are many types of self-service provided and the price is very high.
