Siam Niyom (Simply Thai) in Lambeth

The restaurant has a cosy and welcoming atmosphere, with beautifully decorated interiors that add to the authentic feel. The menu features a wide range of dishes, each bursting with fresh ingredients and bold flavours. I was particularly impressed with the rich, aromatic curries and the perfectly balanced stir-fries. The service was attentive and friendly, making the whole experience even more enjoyable.

Siam Niyom is a wonderful neighborhood restaurant, cosy and welcoming with fantastic food. I adore the Tom Kha soup - well balanced and flavoursome, it makes for a seriously comforting meal. The food is just as good on delivery as in person, and the staff are always friendly and kind.

Our favourite Thai restaurant My partner and I visit often Siam Niyom and we are never disappointed Food is delicious, you can feel the love in it! It definitely worth a try if you are in the area

It’s really good. Just order any dish marked as popular, they are all good.

Amazing foods, great list of cocktails with friendly service, Beautiful decorations, highly recommended!

Real Thai Food, same taste as experienced in Thailand. The best Thai restaurant I have ever tried in the UK.

Update My partner and I went for a second time on a Saturday. We had booked and were seated straight away. Service afterwards was very slow and the food was a bit of a disappointment compared to the first time. Disappointing. First go - all 5 stars Two of us went for the first time on the spur of the moment, about 6pm on a Saturday and we will definitely be back, some of the best Thai food I've had in a long time. I had the vegan drunken noodles and my partner had the pork belly dish with a side of noodles. There was a nice surprise at the end, 10% off as I paid cash. We were lucky but based on how busy it got very quickly I recommend booking.

THE BEST Thai restaurant in whole London. Not any dish tastes like any other. Each item of the menu is rich in taste and flavours, and unique, which is quite difficult to find as many exotic restaurants serve very shallow food. I'm leaving London and I'm sad I won't be able to come here again as often, but I wish them all the best!

Excellent food at a reasonable price. Friendly staff.

One of my favourite Thai place , staff well organised and kind. Prices are competitive and I love the place. Thanks

Great ambience, great food. Loved it. The green curry was one of the best ones I’ve had in a while

We sat at the backyard and enjoyed our dinner. The food was delicious!

Such amazing food and service here. Mains were so flavourful (there is a spicy duck dish which is particularly yummy). My mum said it was like being back in Thailand. Also such lovely owners and atmosphere. Would recommend!

Super friendly staff 👍🏼🇬🇧🇹🇭 Coming from Thailand this is the best Thai food I’ve had in London so far really authentic and remind me off back home loved it and will be back so often.

Yum SCRUM massaman + krapao YUM YUM!!

Just popped in on a whim after seeing it as we were passing by, fantastic service wonderful food highly recommended.

Very disappointing. On paper looks good. In reality it is a combination of extremely slow service, bad food and high prices for what you get. I feel for the team as they were clearly understaffed ( or perhaps just slow...) with numerous complaints about people waiting over 1.5 hours for food. It was not a pleasant experience. Tom kha soup: nothing but overly salty flavourless broth with completely raw mushrooms thrown in right before serving. There was no other garnish except for a sole chilli. Expect a broth with floating raw mushrooms. Chicken pad Thai: ok in flavour but chicken was still pink. Clearly a side effect of the kitchen being rushed. They offered to recook it but we were not going to wait another hour. At least they removed it from the billz but I went hungry and left to cook for myself. Large range of options on their menu including many vegan, gluten free (even beer) and veggie options clearly highlighted. That's about the only plus I can give this place.

Great vegan food and always lovely service. Try the Thai wines.

Booked a table for 5:45pm and turned up to find others outside a locked door who’d been waiting for their booking since 5pm, with a sign saying it’s closed till 5:30. Eventually a waitress turned up and said they weren’t going to open till 6:30pm. 3 tables were just stood outside with no information and we only booked and confirmed by phone yesterday, and had a reminder come through at 4 o clock today to tell us to be ontime! Waitress said the staff had been at a showcase event elsewhere and wouldn’t be back for another hour. Utterly ridiculous as we had driven 2 hours and needed dinner before a show nearby so can’t wait an hour for the staff to turn up for the apparent 20% off this waitress was offering. Apparently the food is good but the service is laughably bad! (Just walked past again at 7pm after eating elsewhere and it’s still closed! What a joke!)

Very good Thai food in Tulse Hill, not far away from the train station. Friendly service on a busy Friday night, no doubt the star of the show is lamb shank curry was soo good. Will be back for sure. Authentic feel to it and best Thai I’ve had in London

Ok food that is ridiculously overpriced - especially as a takeaway which cost us £50 for 2 people and self collection. Ordered the Gat Tod Hat Yai (basically marinated fried chicken) at £13 and got one single chicken leg (which used to be half a chicken btw!) with five slivers of pickled onion. The duck spring roll at £8.70 (!) was two (!) small spring rolls cut in half to make it look like there's more. Lamb Massaman curry was OK but cost £20 (yes, twenty British pounds for a takeaway curry!!!!). Go if you like nice enough food and being ripped off. I won't be returning.

I don’t really understand all of the positive reviews. Food was ordinary, watery unflavoured massaman, soft shell crab was nice but only half a crab served. Food was very expensive for what it was and for a neighbourhood joint in Tulse Hill. 1 redeeming quality was that our server was lovely. Would not recommend or return.

Fabulous flavour packed food and fresh ingredients. Beef massaman and broccoli with pork belly excellent. Green Thai curry is the best here.

Some of the best Thai food I’ve ever had- lovely staff & a warm inviting atmosphere. Thanks!

Incredible food. Amazing service, really warm atmosphere. Great value. Will be back!

Really tasty food and an amazing selection of gin and tonics

This restaurant is a hidden gem. The food is always fantastic yet affordable and staff are attentive and friendly. My partner and I have been going here for years and it’s always a lovely experience. Also lots of veggie options if needed.

Wonderful evening at Siam Niyom. The food, service and atmosphere was great! Hidden gem in Tulse Hill! We will be back again for sure!

A well decorated restaurant with authentic Pad Thai and yellow curry. Taro roll with sticky room was served hot in very delicious taste. You get free spicy prawn crackers if you tag them in IG or FB. Staff are very friendly. Tidy and clean. Good atmosphere. I got 10% off as I paid cash.

Great service and delicious food. The place is actually quite big with "hidden tables at the back. Love the relaxed atmosphere. We had a hard time choosing, meaning more visits will be needed!

I miss very much this place Was my favourite Thai in the area when lived in Norwood

First time at this Thai restaurant, beautiful deco, delicious food and fantastic service. Love this place ❤️

Amazing fresh food and service! Really good vegan menu.

Good local Thai. Very nice food. Service was slow, Prices seem a lot higher than they used to be. Mistake on bill was an unwelcome end to the evening.

This is one of my favourite restaurants, food and service are always fabulous. I'd highly recommend Siam Niyom

Delightful delicious local. Incredible vegan menu- such a great place for multiple dietary requirements

Really, really nice place. Delicious homemade food, charming decor with an eye for detail, and the waiting staff is friendly but professional. Luckily we booked in advance (on a Tuesday) as the place filled up quickly towards 7.30pm. Special offers available on different days. I'll be going back!

Amazing food, decor, and staff were sweet, friendly and super efficient. The best Thai restaurant I’ve been to in a very long time. Will be returning for sure!

Got takeaway, most impressed with the quality! They even used the right type of rice noodles. We had the pad thai and it was just the right amount of sweet and salty. I want to try the red and green curries next! I ordered online for the 10% discount for pick up, and food was ready by the time we drove down in 5-7 mins. Staff were friendly, and I wouldn't hesitate to order again or eat in! Bringing my kids!!

Lovely restaurant and food were OK, I chose the wrong dish, but I will go back. Service was good, too.

The level of the kitchen at this place is outstanding! Fresh product always good. We are habitual client. Strongly reccomanded.

درود خیلی منظره زیبایی داشت و به ویژه استقبال گرم

Disappointing takeaway after previous excellent experiences eating in the restaurant. The Mussaman curry was so hot/spicy that it was almost inedible. Is there a new chef? It’s never been this spicy before. Our servings were also more sauce than meat/veg and the quality of the chicken seems to have gone downhill. It’s put me off going to the restaurant again

Was very busy - can tell it’s appreciated and frequented by a lot of locals. The food is delicious and the staff are very friendly.

Very lovely people and great service and food! Lamb shank was so juicy and tender it fell off the bone. Really good atmosphere and fresh genuine and authentic. Our waitress was very attentive and came quick with our starters and drinks. Food was bursting with flavours!

Authentic Thai food with a wide range of selections! Staff are also friendly and attentive. Will visit again. :)

My favourite local Thai place , friendly atmosphere and nice food combined with positive service.

We went for dinner and really enjoyed the food. The starter was spectacular but the main courses were not much less. Everything was delicious. 🩷 Additionally, the staff is very friendly. We will return for sure!

One of the best Thai restaurants in SW London. The food is amazing and the service is exceptional each time.

We had high hopes for this restaurant based on the reviews but it was a different experience for us. The restaurant was empty when we arrived & still we had to wait for 3 minutes for somebody ro come and greet us. The member of staff at the till was watching us while speaking calmly on the phone. We arrived at 2:10 pm on a Saturday knowing that they were about to close at 3:00 pm. So we decided our orders quickly but again the staff were so slow to take our orders or to even bring us tap water / cutlery. The food was nothing particular. The noodles in my pad Thai were more like a very over-cooked pasta and gave me stomache pain later. All in all, I'm very surprised at the reviews - maybe we went on a bad day.

One of the best, most authentic, and most delicious Thai restaurants I have ever experienced outside of Thailand. Pleasant service, good ambience, highly recommended the soft shell crab and the Thai milk tea. The dishes use authentic ingredients like Galangal, Lemongrass and Thai Yellow Pepper, for flavours that are truly difficult to find elsewhere in UK. Nicely balanced, and not too sweet like in some Thai eateries elsewhere. Loads of vegetarian options. Pay in cash to get a small discount.

ordered takeaway from here with family, the food was out of this world delicious, will be ordering again :)

A lovely restaurant, with a small family feeling. The food is great, the service is excellent and the prices are reasonable

Favourite Thai place in London! We are regulars here (both eat in and takeaway). You *have* to try the Coconut Braised Beef. Genuinely one of my favourite dishes ever - salty, sweet, tangy and spicy all in the right proportions.

My favourite Thai restaurant in London. Outstanding food and lovely staff.

Great place! Loved the tamarind chicken especially. The chicken was succulent and fragrant. Everyone who works there are also really lovely. Thank you for a wonderful meal.

Last minute dining out and cannot fault it. Delicious food, great ambiance and service. Kids ate everything on their plate. Will definitely come again.

The place is a bit expensive but the food is amazing. There are not much restaurants like Siam Niyom in this area so it is very convenient for dates in walking distance.

Amazing food and so full of flavour. Great range of drinks, including local craft beers. Presentation was lovely and staff were so friendly. The garden is gorgeous and a very nice place to sit and eat on a warm evening.

Lovely homestyle Thai food, lovely service provided by the owners, all round engaging and authentic experience

This place could rival heaven. The aroma that came from here was enticing the decor was awesome, but the food oh the food was bleeping sensational they got a peanut sauce here a they could bottle and put on everything and anything. sorry those of you with nut allergies. I highly recommend a visit but save you self you have a belly busting treat

Hustle - bustle vibes, good food, great cocktails!

Amazing food, full of flavour, great service,cosy atmosphere 5*

Such a little hidden gem. I had a beautiful pork dish with a nice kick to it, the food was fresh and cooked really nicely! The choice of drinks especially the G&T was such a treat also. Very delicious mine as I had fresh ginger in it if anyone is interested in knowing the options. The staff were friendly and accommodating, didn't have a booking and we also were able to sit outside at the back while the sun was still out. Real nice, and right by Tulse Hill station which has lots of good connections when traveling from certain areas! Solid A***** LDT x

Great food and service. Love the ambience as well!

Great food, friendly service and not bad value for the quality at all

My first time here on Saturday night and I was NOT disappointed at all. The food was great with such friendly service to match. Authentic flavours as the the cooks were Thai so that's always a good sign. The decor of the restaurant is lovely and a very good atmosphere. Highly recommended and I will be back when I am around the area!

I ordered a vegan green curry for delivery and what arrived was quite a disappointment considering the price. The ratio of curry sauce to vegetables/tofu was way too high. There were probably 5 bits of tofu in there. The selection of vegetables did not lend a pleasant texture... it was mostly bamboo shoots, lotus root, and turkey berries (pea aubergines). Furthermore, the curry sauce itself was very mild and boring. Not worth £13.85.

Hi Meeta and staff sorry for the late review. Just want to say thanks for the lovely Graduation night my daughter had with her 18 friends at your restaurant in late January 2023. It was a great atmosphere. Great food and the music too. Plenty laughs a buzz to the atmosphere. Friendly staff. A place that I can recommended. Loved the modern decor. Never thought to find such a place in West Norwood. But I have.

Friendly staff and delicious meals! Enjoy Thai food at is best!

I never thought that we would leave with a £50 pp bill, but we did. I blame the enticing menu, of which I needed considerable help from the waiter to decide. The curried sea bass was extremely good, so good it will warrant a second visit. However, across all the dishes, portion sizes were disappointing, and not something you expect when heading to a Thai restaurant. It's the reason we ended up buying dessert, and it was eventually the reason I ended up buying some extra food in the Co-op opposite to snack on after. So, some impressive, new cookery, which was fun to experience, but it's not great value it must be said. You have been warned, but try the curried sea bass as a treat if you can.

No response for delivery riders No respect ,nothing Waste of time ⏲️ They ignore if you still visible to them Have to wait 10-30min for single order If you guys don't know ,how to manage delivery, then shut down you delivery machine , why you guys want to waste and ignore delivery drivers

Most delicious Thai food I have found in London with amazing vegan options!!! Loved it so much!!!

Lovely delicious food and really nice service.

Omg , if you like spicy you should try e sarn , classic ever , but if you like normal ,moo kronor pad krapao

I m Thai , unforgivable food , taste all same as in Thailand, you cannot find any same in London , 5 stars ++++

The family celebrated a birthday here in October. The service was top notch. Staff were patience taking all our orders. Food was nice however a bit pricey.

Wonderful afternoon spent here, enjoying great food and atmosphere. Food quite authentic. Service friendly and prompt. Well worth a visit.

Been living in West Norwood for over a year but went there for the first time only this week. Wished I had been there before. I tasted new flavours for the first time in ages. The good looks and tastes so authentic, nothing like the usual Thai street food found in some of London's markets. Customer service is great too. Love this place!

Ordered takeaway from this place. The flavours were lovely but it is incredibly overpriced, the vegetables were practically raw and the rice (which cost £4 for a tiny portion) was essentially a brick because it was so solid. There's sticky rice and there's needing a knife to cut it properly. The spring rolls were so tough and chewy. I was really looking forward to this but was incredibly disappointed. Perhaps in person it is worth it but I would never recommend this restaurant to anyone.

The food and service are always good here. We went for their pad Thai special. £19.95. Not cheap, in fact probably the most expensive pad Thai I have ever eaten but it was amazing. What wasn’t amazing was the offer by the waitress of prawn crackers for the table as soon as we sat down. Of course we said yes. Other Asian restaurants prawn crackers are either a) free or b) a couple of quid. Fast forward to the bill arriving. £8.40!!! For prawn crackers. I know cost of living blah blah but still! I find it a little sly to ‘offer’ prawn crackers only to charge ‘lobster’ prices! That’s my only criticism. The rest of the evening was great.

So I just want to start off by saying the staff were lovely and friendly, and the decor/ambience was great. We travelled specifically to Tulse Hill to try this place out so had high hopes from the great reviews. I don't know if we just got unlucky with the chef, or this was down to what we chose, but we unfortunately left feeling rather disappointed. We ordered the Salt and Pepper fish as a starter, which was overwhelmingly fishy tasting and not that nice. Then for the main I ordered the "signature" Phuket chicken. This was incredibly dry and tasteless, and came with no vegetables, and was a huge let down. My friend ordered the Pineapple rice which they reported was just "OK".

Delicious experience from setting to hospitality to food and ambiance. Lovely. Enjoy.

Good authentic food with high quality ingredients and presentation. The staff are very attentive and friendly. Will definitely go back again.

Wonderful neighbourhood restaurant - excellent food and service.

Delicious and beautifully presented, authentic Thai cuisine! The lamb rack was very tender and bursting with flavour. Will be back 😊

Some of the best Thai food I've eaten. Great service and friendly staff.

Really tasty food nicely presented served by efficient friendly staff. It was very busy and a little cramped but nevertheless recommend.

Wonderful authentic food…it’s one of the best Thai I have had in London.

2nd visit and this time we went there for birthday celebration, as always foods was fantastic plus friendly service..most surprisingly they gave us a little birthday pudding in the end :)

First time at this lovely Thai restaurant and I cannot highly recommend enough, the food was very nice and the staff were really nice and friendly. It's been a long time since I've had such great friendly service. I had starters, main and dessert and all was so good. I cannot wait to come back and try other food on the menu.

Food was great. But beware that the 15% discount on dine in on Mondays as advertised on the website is a scam. We had to pay full!

Great food with many speciality dishes, Try the Northern spicy sausage or the lamb Massaman curry. One of the best Thai restaurants I have been to.

Delicious food, professional and very welcoming service. Will be back 💯.

Delicious authentic Thai. Has a large vegan menu and the best green curry ever! The mushroom Tom yum is so flavourful. A really beautiful restaurant to dine in! One to beat!

Fantastic neighbourhood restaurant. Reliable, exceptional quality and authentic Thai.

I've had two takeaways from Siam Niyom now and each time has been absolutely AMAZING! I've had the braised beef coconut curry and the Tom Kha soup now and both w reeunreal. My partner had duck and chicken wings and was in heaven. Can't wait to actually sit down for a meal inside the restaurant.

Amazing food. Very friendly staff.

Really enjoyed this restaurant. Food is fresh and lots of interesting flavours. Some good cocktails too.

Superb presentation but tasteless dishes, watery curry, meat cooked to the extreme, dry and tasteless, all charged at the price of a very good restaurant. A taste for westerners without a palate. Go to the Thai Duck Deli, it's the opposite !!!!
