Great pre theatre dinner, lovely food great service

Perfect Bento lunch before theatre matinee. We had the downstairs to ourselves but it didn't matter really. Lovely location and super friendly service.

Extremely disappointed by the manager of this restaurant (photos included!)

I went with my partner for dinner. We ordered black cod and found 6 fish bones in it. I've been to many restaurants that serve black cod before and all of them were properly deboned (especially if you're paying £30+ for the cod!!!). My partner actually swallowed 1 of the bones. I reported to the manager (not hoping for a refund or a new dish, just wanted him to know the situation) and he reacted in a very negative way. He defended his chefs and said that it was impossible to debone everything. I appreciate that he's trying to protect his chefs but finding 6 BONES that are as long as 2/3 of my finger is definitely not an excuse. Imagine if someone choked on this?! As I mentioned earlier, all black cod dishes should be deboned properly as it's basic restaurant rule. Plus, finding bones that long should not be a hard task if deboned properly. In my opinion, the manager should have just apologised and not make any excuses and make me feel like I'm in the wrong for reporting an issue.

Regardless, all the other staffs were really nice to us and the food was good. It's such a shame because I don't think I would go back there after my encounter with the manager.

A good solid robust place to eat. Nothing to fancy but nice place to visit. Would go back.

Our overall experience was very good. The restaurant is not very big and therefore the tables are quite close. The food was very good and friendly service. We were served in good time and correctly. The wine list is limited by London standards but a pleasant Rioja was had. Will definitely re visit.

Outstanding. Really fanatic. Nice welcoming team. Great ambiance. Food was to die for. Really delicious.

Uni restaurant offered a relaxed yet busy environment with great, friendly service. Food was spot on with option to mix and match or go whole yourself! Great experience

The staff were wonderful and the highlight of our surprise birthday dinner. Friendly and welcoming ambience, just what you need after a day of rain and a very grey London!

Terrific little restaurant

A lovely place. Service could have been more cheerful. Portion sizes are very small for the price. The cod was delicious and there’s an impressive selection of sushi

Nice staff

A stand-out restaurant close to the Victoria Palace Theatre where we went to see Hamilton after dinner at Uni. The food was exciting and beautifully crafted. Japanese with touches of Peru on the menu. The dinner was made especially memorable thanks to our outstanding waitress, Natascia, who was knowledgeable, courteous, yet unobtrusive.

Best sushi we’d ever had! Bit pricey but very tasty.

The food is absolutely delicious. One of my favourite places to eat.

Very beautiful, intimate venue with attentive service and spectacular food

Unfortunately, they had very little on the menu available due to a broken cooker. We left instead of staying and eating something that we didn't want to and didn't want to risk it with the raw fish because if the cooker is broken who knows what the refrigeration was like. Would not attempt it again.

beautiful & delicious meal / lovely ambiance & attentive & pleasant service - thank you A. Ambort

Amazing sushi, wait staff were fantastic and gave great recommendations. Would highly encourage anyone to visit.
P.S. make sure to try the cocktails!!

Delicious but portion sizes very small and prices very big.
Drink prices were especially extortionate.

Amazing food and great value, and great area for the theatres.

My mum and I are huge sushi fans. Uni was disappointing. The service was very slow and the more we tried to get someones attention, the less we were seen. The yellowtail sushi was fishy and tasted like it had been frozen for ages. The Salmon was OK. The Toro was terrible and cut really badly. The California roll was ok. The Uni tasted not fresh at all and was toppled over on the plate (super expensive to serve it that way). We were just unhappy, especially with how expensive sushi is in the UK... There are much better places in Knightsbridge which are at the same price point and the quality is significantly better. The music was also really loud. One great thing was when we told the manager about the toro and yellowtail he was apologetic and took them off our bill which we appreciated. Unfortunately, we will not try UNI again.

Food is ok for a pre-theatre meal, but the place is small, and the service is not efficient. We enjoyed sushi, but the portions were small.

Waitress had no idea on the menu and could not answer questions, and wasn't interested in seeking clarity from other members of staff. Some dishes very over priced and you can find much better value in central London. Restaurant was empty for pre theatre session, surprisingly for a restaurant with good reviews on a Friday night. No toilet paper in the bathroom, rather strange given it had just started dinner service. Definitely would not recommend.

Great food

Staff were nice, but I was quite disappointed with the serving sizes of the tacos (a joke) and the California Rolls - tasted nice. But was starving when I left.

My partners food was fine, and had no complaints.

Excellent dining and food experience.

Lovely sushi, but the service was very slow on a Friday evening at 8pm. Lots of other tables looked annoyed as well.

Amazing sushi restaurant! Food is excellent and the service very friendly. Very close to Victoria Station!

good food and friendly service but very expensive, even for belgravia, and prices out of kilter with the setting.

Massively overpriced and mediocre

Second time in UNI. Amazing food and really fresh sushi. One of the best sushi restaurant in London. Staff was lovely and helpful. You have to try the miso black cod!

The food here is delicious but the portions are miniscule. Be prepared to pay a lot for a very small amount of food!

Food is great, but we waited ages for our food, when we told them at the start that we had a theatre booking. Different starters came at different times. Difficult to get any waiters' attention.

Very overrated. Went prior to the theater, told the waitress when we got there our schedule, 1 1/2 hours time allotted. Were not served main course until we had to leave, so left as it was served. Took several attempts to get wait staff to take drink orders.
Miso soup was terrible, sushi unremarkable. Price too high.

Service was fantastic. The food was so so. I've had better sushi, the seaweed wrap was tough.

Excellent food if a little expensive, but you do get what you pay for. Staff are friendly and acomodating and happy to advise on what and how much to order. Wine list is small but covers all the bases. Both upstairs bar seating and downstairs tabled seating are cosy but are comfortable and don't feel at all cramped

Too expensive for what it is. Too many deliveroos drivers if you are sitting at the counter
Food was ok but for the price there are better place

Food wasn’t that great.

Food was fine, service was good esp. allergy awareness but prices were astronomical.

Unfortunately very slow service. I had to wait for miso soup for over 30 mins when the restaurant was virtually empty. Food is good but overpriced. I used to like the place but no longer.
