Oishii Japanese Restaurant in East Hertfordshire

Super tasty authentic food. Friendly staff and a lovely chilled vibe.

This is a beautifully decorated restaurant. Perfect for a romantic date or treat. I have eaten so much sushi in my life & in different parts of the world. This is EXCEPTIONAL!!! Immaculately prepared with beautiful presentation. Tastes fresh, original & delicious. I would especially recommend the spicy tuna avocado roll & spicy salmon avocado roll. A lovely selection of crunchy pickles which really enhanced the flavours of the meal. Their tofu katsu curry was really wonderful. A warming filling dish. The tofu is delicately prepared with lovely rice & very tasty curry sauce! I love spinach & the spinach goma (with sesame & miso) was the best spinach I’ve ever eaten. The prices were good for the quality of food. We were very happy after our meal!!!

Really nice atmosphere and decorations. Food was amazing and good variety. Highly recommend the status are lovely.

beautiful restaurant with absolutely beautiful food would 100% recommend to anyone. service is amazing, typically served by a lovely guy called june who is fantastic as well as polite and always makes us feel very welcome. always a lovely time here :)

The food in this restaurant was simply exquisite. I had a Gyoza starter and some Duck rolls for main and they were some of the most flavourful dishes I have had in the area. Nice decor, with bamboo decorations and just a nice feel to the restaurant. I would highly recommend this place.

Lovely, friendly staff. Food was absolutely delicious, beautifully prepared. We would definitely be happy to return here.

Literally the best, I would (and do) go here over the fancier places in London. Best sushi I have had since moving from the Pacific! This is our absolute go to favorite restaurant, the food is always super amazing quality and tasty!

Place jas a lovely atmosphere. However I feel the dishes lacked flavour and the duck was chewy and over cooked. I enjoyed the mochi desert and gyoza.

Great food and service 👌 defo be back soon

I WOULD HEAVILY RECOMMEND AVOIDING THIS PLACE!! Ruined my Friday night meal and ended up dining at Mr. Tanaka's not far from this pathetic managed restaurant. Got to Oishii to be told we only have the table for a limited time which was totally fine. The service started off well and then ended up being a total shambles. Got asked twice by two different waitresses for drinks and food. I even got the same drink handed to me twice. So many miscommunication between the waitresses. I then ordered more food and after waiting for 25 minutes we asked how long it will be as we were conscience that we were running out of time on the table. ONLY TO BE TOLD THEY DIDNT SUMBIT THE OUR FOOD ORDER. So if we did not ask then we would still have been waiting there. Totally unprofessional! I told them to forget the order and to give me the bill. They didn't even bat an eye lid and handed me the bill. No apologies or nothing. I wouldn't want to part any more of my money with an establishment like this. Management really need to check on there staff and train them properly. Food maybe good but ruined when you don't submit orders to the kitchen and loose out on money. I have been in the food industry for over 15 years and you guys need some serious help with front of house! I would definitely recommend Mr. Tanakas and just avoid this over priced disappointment of a "restaurant" Thanks again for ruining a Friday night!!

Beautiful food. In looks and taste. Really prepared with effort it's obvious and it tastes amazing. Lovely and fresh. Small restaurant with a nice decor and comfortable atmosphere. Staff are friendly too

Fabulous food, the golden pumpkin cakes that come with the Salmon Miso Teriyaki are delicious and certainly a highlight. Would highly recommend Oishii to anyone looking to experience Japanese Cuisine in Hertfordshire

Really enjoy this Japanese experience. Not so many veg options though

food is fresh and tasty, love this restaurant so much.

We visited Oishii today for the first time based off my partner’s friend’s recommendation and we really enjoyed our meal there! Staff were lovely and friendly and the atmosphere was great - highly recommend and would 100% revisit!

no problem coming early we booked it ASAP, it just came earlier than what they said it would which is great! the food was amazing too, highly recommend!

Had dinner here tonight with family. Left disappointed the rolls all had more veg than fish in. The fish tasted like it had been frozen. Seabass was disgusting. I’ve been here a lot lately with friends and family. But after today I won’t be returning. 5 pound for a small bottle of beer and then adding service charge when we spoke once to the server to order and once to pay is also not on. Seems greed has take. Over here so won’t be returning.

I went in to order a takeaway. Luckily I checked the bag before leaving. One of 4 ítems was missing PLUS I had been overcharged by £18!!! Check your orders and bills people….

Tasty food. Warning about food poisoning on the inside cover of the menu (no doubt an instruction from the lawyers) is not terribly appetising. On asking the staff who gets the 10% automatic service charge, they said that 5% goes to staff and 5% goes to the owner. I suggest if the owner wants 5% on the margin, they put up the prices 5% on the menu and take their chances on customers choosing not to eat there. I hate this practice but sadly it’s all too common. If it’s not the case, I suggest the staff are better informed. The food was lovely and we’d go again.

Fantastic food, best in a long time 👍

What a lovely restaurant. Couldn't fault anything. Given 4 stars as, although we expect to pay a fair price for a decent meal out, we felt this was slighty on the pricey side. Friends had mentioned it was a little more expensive than you'd expect. That said, the food was absolutely delicious & beautifully presented. The service was very good, friendly, attentive & quick. Will visit again & would recommend. Thank you Oishii

The food and service is amazing.

The driver said he had tried to give my phone a call and ring on the house buzzer. Neither of these things happened and when I called the restaurant, they said they knew about this and will just have to send him back out for delivery. A while later he did then call. By this point all of our hot food was cold, and cold food warm, which with sushi, is obviously not ideal. When I raised this concern with the restaurant before the driver arriving, they said there’s not much they can do. Our food was

Lovely atmosphere and great food. We all had seabass which was delicious. There was a little mix up with our order which was promptly resolved with the utmost care and courtesy. Definitely a new favourite place. I had a lovely quiet evening with a couple of friends.

Fabulous food could not fault it

Another delicious lunch at Oishii. Been coming here for years and everytime they deliver. This time Mamion and Kat were the servers. So lovely; great service. The bento box lunches are such good value and the quality is excellent.

I went for dinner here with my partner last night and it was fantastic. The food was delicious, the wine was great - I would highly recommend the Katsu Curry! We are new to the area and definitely will be coming back here. At the end of the night I left my bag at the restaurant and the team were kind enough to drop it to my house that evening. Could not recommend enough!

Always great from here whether eat in, pick up or delivery. The Crispy Scallop Roll is a must.

Quite expensive for what it is, fish isn’t the best and they’ve adjusted the rolls so they are smaller, but the prices have gone up… not great value for money.

I just ordered delivery, and although I will say the sushi is pretty good, it’s by no means amazing, and it’s overpriced compared to other much better restaurants. I ordered Ikura nigiri which is salmon roe and they charge £4.99 for one piece - they sent tobiko which is flying fish roe (the little red roe) and inferior and much cheaper. I called the restaurant and they spoke to the chef who said they no longer sell ikura . So I asked why is it on the menu - they said manager hasn’t taken it off. Then I remembered , we came here last feb for Valentine’s Day to eat in and the exact same thing happened. On principal I find this very insulting to the customers assuming people don’t know the difference it’s like ordering tuna sashimi and being served tinned tuna. Not to mention this is ripping people off. The food otherwise is decent but I won’t be coming back for this reason.

Excellent sushi, lovely staff and nice atmosphere.

The food was absolutely incredible! We had the duck rolls, chicken gyoza, vegetable tempura and katsu Don. However, once we had finished our food, we were forgotten about. Nobody came to offer us a dessert menu or the bill, and we spent longer sitting waiting than we did eating! Shame about the miserable lady serving us but the food was fantastic. Next time will be ordering a takeaway I think!

Ive moved to Hertford over a year now and so far my experience with Oishii was 5/5 until today when I’ve received something what I can’t even describe. Rolls without filling? Plate complete mess? What is this for 40 pound??? Never ever again!!!!!!

Food is not edible and need compensation as can’t even taste this mess

Everything about this restaurant was amazing. The food portion was perfect and tasted great, the atmosphere felt authentic, and the staff were incredibly friendly. If you are ever in Hertford I highly recommend checking out Oishii. 10/10 place, will be eating here again.

We was here yesterday and can't recommend this place enough. The food was delicious. Can't wait to come back.

Sushi was really good, a bit warm for my liking but overall very good service!

Came here for a date night with my other half before seeing an orchestra at The All Saints Church. Had Chicken Yakitori and Gyozas for starter Sumiaki Serloin Steak and Salmon Donburi for main. Sides were Kimchi, Wakame Salad, Egg and Garlic Rice and Mixed Japanese Salad. Drinks: Sparkling Water and Sapporo. Overall, the food, atmosphere and service was great. The gent serving us was amazing and paid close attention with our order as well as asking if we had any specific dietary requirements. The only thing that was off putting about the evening was a pair of teen girls sitting there giggling and stabbing their food with chopsticks creating a bit of a scene. Not really how you should conduct yourself in a small restaurant, but what can you do? Total cost £71 (including 10% service charge) Will definitely return in the future

Hadn’t been back from Japan for long before going here and honestly I felt like I was right back there. Food was amazing quality, and surprisingly affordable for how good the food was! Going again in a few weeks and probably again after that

Really disappointing this time. Bland hot pots of udon noodles, sushi was on the edge of passable. Restaurant was cold (lucky for me was sitting on a heater). Only good thing was the great waiter. Lovely chap.

Delicious food, friendly staff.

Fantastic, fresh & authentic sushi. The atmosphere was great and we all enjoyed ourselves very much. Also the price was reasonable when considering the quality.

First time for us here..had such a lovely meal... Staff so friendly, our server was friendly and knowledgeable. There wasn't a dish we didn't like. Would definitely return.

The food was not up to much compared with other Japanese restaurants. Poor quality and overpriced.

The miso bowl I had, had a grimy lid. Food though was lovely and fresh. I'd go again no bother :)

This is a great place to eat, but avoid at all cost ordering a takeaway, meal was an hour late and the meal arrived cold. The soup dish had spilled into the bag, so no soup. When I complained, there was zero comprehension that my evening had been disrupted and complete denial that the one of the meals was not edible I.e. it was in a bag. The owner avoided at all costs to speak with me and simple shut me down with an I don't care attitude. She needs to try harder one star. In addition, the staff that took the compliant laughed and mocked my complaint as they out the phone down.

Unprofessional, working hours show open, drive 30 minutes to buy £100+ worth of Sushi and Sashimi and i find it closed. Never again. PS. due to the owner response, denying talking to me on Friday 29th of September, I have spoken to the mother and to the two sons (if they were the sons) while they was outside Don't take me wrong. Food is excellent!! I have nothing to complain about the food! And i have ordered before, however, if I look on Google and the shop shows is open, I called twice to make sure and nobody answered, I think by common sense that the shop is open and busy due to be the only Japanese sushi/sashimi open at that time in that area!! Please adjust your time because I drove 30 min to go finding the place closed and 30 min to go back having to drive another 30 min to buy somewhere else !!!!

The staff were lovely and the food was SO good! Highly recommend

Used to love this place. Quality went down a lot. Service has never been their forte, but the food made up for it. Not anymore I’m afraid.

Taken my parents and friends here a few times and never disappoints. the food is always excellent and the service second to none. while it can be quiet its a hidden gem in the centre of town well worth a try. look forward to returning soon

Food arrived on time, but they messed up my order didn’t get my crab roll got 2 duck rolls,

Great food, friendly service. Owner Elle gave great recommendations - we came in for a quick lunch as the lunch menu looked good with bento boxes etc but ended up getting a sushi boat! Fish tasted really fresh which is a must. No immediate parking outside (only max 30 min stays) but there was a parking garage round the corner so it was still quite convenient.

Bone in chicken sushi, absolutely disgusting. Sadly i haven ordered before and its been nice maybe it was food left over from the night before.

A quaint little restaurant tucked away off the street. The food is always impeccable and the staff friendly. The prices are reasonable and the service is always pretty quick.

Two staff at once to begin with then nothing. Some spectacular dishes to other tables but menu doesn't hint at that.

Incredible sushi. I’ve never been so blissfully full in my entire life. Would 100000000% recommend. Also the server Callum was wonderful. Deserves a raise! He was so kind and friendly. Made us feel very welcome. Also such a lovely atmosphere. I felt extremely relaxed on top of eating insanely delicious sushi.

Always delicious, and great service!

Go there regularly to eat. Excellent food range and clear pricing. Highly recommend the Lunch time menu.

We really enjoyed the food here.

Very cute and cost japanese restaurant. Really good food and service. Better options than other places near by. I eat from here often and highly recommend!

Looking at other reviews we were unlucky. My beef was cooked so as to be hard and tasteless, My wife's chicken was also cooked to the point of being rather dry. The rice was also overcooked. The food was nicely presented, and the staff friendly and helpful. The atmosphere would be much nicer after dark, but on a hot day with the front open to the street, with the tables on the opposite side of the street providing quite a lot of noise, and very bright light coming in, the internal decor was somewhat defeated.

We visited recently and ordered a big variety of the sushi- all was amazing! The service was prompt and friendly, would definitely visit again.

Wow what an incredible place on a buzzing Saturday night and the food is excellent service is fab and the staff are very welcoming and knowledgeable about the menu 🤪🤪🤪🤪🤪🤪And this is in my hometown

Great food and very good service . Can't wait to return

Just lovely. Lovely food, lovely atmosphere, lovely staff. Had a wonderful evening in a very relaxed and cosy environment. Hats off, you nailed it. Thank you

I'm my humble opinion, the best sushi I've had. I've visited this place years ago and has been the high mark for me for sushi. I always wanted to return and enjoy the food again. I had a chance to return as I was in the area and it was as great as before. Still the high mark for me, in my humble opinion.

Such a nice place, special sushi are delicious, staff is nice 😊

Quite a small place and not a lot of table space for food and drink. However, the food and drink are delicious and would visit again!

I’ve had Oishii many times before but it’s clear to see the standards and portions sizes are dropping. Had a shocking meal tonight £9+ for ‘chicken katsu’ with no sauce and all the food was cold. Last time I order from there.

Great food, some was a little damaged and they forgot chopsticks

Food was really amazing tonight best takeaway I’ve had from here. I had a bad experience other week but gave them another try. Food was packaged better aswell so didn’t arrive damaged or covered in wasabi.

Did not provide what we ordered

A very rare find outside of London. With great tasting sushi at a reasonable price. Between 6 of us £45 each left us very full and satisfied. The only issue was quite slow service however it was a busy Saturday night. Perfect otherwise

Hair in my kimchi, manager was absolutely awful in dealing with our complaint, told us we ordered too much food and thats why we aren't eating the food with HAIR IN IT

Late cold and missing chopsticks every time we order. Used to be my favourite take away but not sure what’s happened

Food is really good. That’s why we kept coming back. Unfortunately since they re-opened after the pandemic the service has been slow, inattentive and sometimes argumentative. If you have a table of more than 2 no one will remember what you ordered. Drinks, starters and mains arrive at random. Staff could use some training on table service and at least basic knowledge of Japanese food (for example a difference between teriyaki and yakitori sauce). It’s a shame as Ella’s really nice and I wish her all the success but for the reasons mentioned above I can no longer recommend this restaurant.

It was a great date night out would recommend

I love this place. Surprised they have added the word ‘boat’ to the sushi platter and added £10 to the price but no extra food!

The place is cold, with small heaters dangerously running under the tables. The food doesn't taste fresh.

Ooshii is always excellent. Superb quality sushi. Also excellent chicken teriyaki, chilli squid, chicken gyoza. We had really tasty yaki soba too. Also the desserts were lovely especially the mochi. The staff are friendly and efficient. I have always found the standard of food here consistently excellent and very authentic sushi and sashimi.

The food is simply amazing. I've had sushi in many places, but this was top class

Ordered food and it shows up over 2 hours late. I’m never ordering from or going to them ever again. Very unhelpful customer service, did not offer any freebies or discount to make up for the delay

I placed the order very early, and still it took 2 hours. When I called they had an automated response. When I finally got through there was no apology. Just repeats that it was ready “in 5 minutes”. The hot dishes were cold and the rude phone call was unforgivable.

Great sushi, duck roll was perfect. Beef roll is a good idea but in practice was cooked a little too rare for the cut of meat, a bit too chewy for sushi. Would work a lot better if cooked in some sort of sauce. Yuzu sake is great and can be bought in many places if you find you really like it like I did. Staff were very attentive although as per usual with the UK it takes some time to request the bill, then additional time to actually pay (as opposed to receiving bill and payment unit at the same time). But that's just personal preference. Will definitely be back as there's plenty of great stuff on the menu that I still need to try!

We've had takeaway a few times but decided to eat in and we're not disappointed. Everything was really tasty and fresh

Good food, but service was poor. Had to ask for missing items that were ordered. Staff took an empty plate from the center of the table, leaning over food we were eating at the time, and towards the end, kept wanting to take the plates we were still eating from. It wasn't even a busy Saturday night, so there was no reason to be rushed.

I’ve ordered delivery frequently from this restaurant. The food has always been pretty good however every time I have ordered it has been minimum 1-2 hours later than the estimated delivery time says. Literally every single time. I don’t know what’s going on with the delivery process but it needs to be looked at.

Love this place . Food always so fresh and tasty

Delicious sushi and quick efficient service. Great evening

Not sure what I was expecting but this place is for someone who doesn’t know/understand good quality food/flavours. Very cheap and bland. And I am a sushi fanatic, I’m deeply disappointed. 😮‍💨

Another great Hertford experience. Just a little bit different, great selection on the menu. Worth getting to know Japanese dishes. Nice service, friendly and welcoming 👍

A favourite of ours for eating out in Hertford. The restaurant looks lovely and staff are friendly and helpful but above all the food is always delicious. Highly recommend.

Not very tasty, didn’t taste like much sadly. Overpriced for the blandness and the delivery came smashed covered in wasabi and ginger when I asked to not have wasabi or ginger.

Excellent food, very friendly staff even if there was a bit of confusion with the orders. One dish was wrong but we kept it anyway and it was good.

Fabulous food, absolutely delicious. Quality as good as any top West End restaurant. Service faultless! Full on a Monday night - says it all!

Gorgeous food but service was appalling slow. I'd finished my main before my friends main arrived. Asked for bill twice, then asked for dessert menu so I could have a pud before the bill arrived. Neither arrived and had to ask again for bill. Better service in the Wimpy at the Old Pond. Walk past and go to Old Siam, superior in every way.

Best sushi I've been to and I love it here

Wasn’t expecting to be impressed but the food was amazing. The rolls were amazing, The black cod was an absolute surprise. I’d say on par with top London restaurant versions but the presentation did let it down. When it arrived I thought oh dear but wow I was so wrong. I’m looking forward to returning.

I would like a refund as the food was cold.

Asked for genmaicha and they had none! Already a bad start. My partner and I ordered a bento box each plus a veggie tempura. Food didn't take too long to arrive but unfortunately the quality is below par. The sushi was poorly cut (especially for the tuna) and one was stale/extremely fishy. The tempura batter was too thick and not crispy enough. The staff were attentive and the restaurant is quite decent but the food is sadly subpar.
