Food is good. Service is good. Though sitting outdoor but fantastic weather today makes everything perfect. The only thing not that great is the table is too small.

When we arrived, we was standing around for 10 mins or so waiting for a table to become available.
we got a nice little spot with a bit of sunshine which was nice.
Waitresses were very polite and helpful.
The food was nice but I did expect better for the price we paid.
The hot sake was really nice.

We were outside, but luckily the weather was great. Food was great.

Excellent food and friendly service

Great local Japanese restaurant serving great food by friendly staff

A lovely independent restaurant serving fresh food with friendly staff. We went the day after lockdown, so had a table outside, but will definitely be back for the full experience.

One of the best sushi restaurants in London. The staff and owner are always charming and attentive. The food is amazing.

It is amazing food and very good and attentive service. It is very pricey though.

Good sashimi, love the toro and the butterfish! Worth the price compared to other high end JP restaurants in town

Pretty decent. Limited selection if trying to avoid vegetable/seed oils.

The restaurant was cold, the service was extremely slow. The food was burnt and not tasty

Excellent clean fresh classic sushi. No over engineering.

Was ok. Large menu with American style sushi rolls, unfortunately the one we ordered was swimming in Yuzu sauce that drowned all the fish flavour. Good sake. Dining was limited to 75 minutes which we were only told on arrival.

Kazu is what you'd expect from an real Japanese restaurant (wagamamas is not a Japanese restaurant)

While the servings are small, and the bill can rack up. We did get a 25% discount, which made it a very pleasant meal and just the right value for money.

Really fantastic food at good value

delicious fresh sushi and nice side dishes. Service was great too!

I love this place - the food is a cut above. That's because the owner of the business is the chef! You pay for good food but it is definitely worth it. I'll be ordering take away during lockdown part II. So yummy!

Outstanding food and service. Excellent drinks menu.

Not bad. The blue fin tuna is good. But the soba is a little soft

Returning customers and very happy every time. Very fresh fish and the waitresses are very helpful and friendly!

It took almost an hour to get our food, and 20 min till someone noticed we wanted the check.

Luckily the food made up for the service and REALLY long wait. After 1 hour our bottle of wine arrived.. we were starving by the time the food arrived and we noticed tables who arrived after us were eating before us.

The staff were apologetic and gave complimentary sushi, however finishing our meal we were not even offered dessert and they promptly came over and asked us to pay the bill, which we found quite rude.

Won’t be in any rush to return, it’s a shame as the food was good but experience was let down by the wait and lack of customer service.

Delicious sushi - plenty of unique rolls. Good sake. Friendly staff in a great neighbourhood!

Had a lovely meal. The wine was good. The staff were ok but a bit awkward. I would definitely go again. The meal was a little pricy though but most Japanese restaurants are.

Went here for a nice dinner - amazing service, and amazing food. Definitely on my best go-to restaurants list for London.

Excellent quality and choice of food. Very friendly and attentive staff. The restaurant is nicely furnished and has a good ambience (despite of PPE measures currently required). We will book again!

Great food and staff

Superb authentic Japanese food in a super environment with friendly and helpful staff.
Tasty sashimi and sushi all beautifully presented. Fun to sit at the counter and see your food being prepared and the quality of the fish being used. Will definitlyl return

The service was friendly, the restaurant was nice and peaceful but not lacking in atmos and the food was great.

We were in a basement room with one other table. Nice atmosphere and the service was attentive. Food was excellent- black cod was sublime. Really enjoyable meal.

Excellent food. Good service. I will come back again.

Really nice place. Really nice food but service charge is quite steep. Still very happy with the food and service.

Food was good, service was fine.
We were a group of 3 and ordered tea, expected one pot to share but received small tea pot each so had to top up with hot water. They wasn’t very attentive to our table.

Really good atmosphere and friendly staff. We ordered the steak and cod fish. Cod fish was fresh and nicely braised - the portion could be slightly bigger though. Overall, very satisfied with the quality

Very tasty sushi and yuzu sorbet, planning to go back again soon as they are doing the £10 off in Sept too

Authentic Japanese food! Delicious! but space too small,can’t really achieve the social distancing

Second visit and once again a wonderful experience all round. Some of the best Japanese food I've had. Great variety and delicious flavours, all perfectly prepared. Really good portion sizes so very good value. Perfect anniversary meal.

Kazu used to be a neighborhood gem but something seems to have gone wrong. The service was really poor. We tried to get the waitresses attention to order food a number of times with little success. It got so bad that people at other tables started telling the waitress we were trying to get her attention. We had to ask for water about 7 times before actually getting some and our food arrived an hour after we ordered it.

They’re clearly very short staffed and were not equipped to deal with such a large number of diners.

Extra slow service.
No staff.

I amended the booking to expand guests and was told we would be moved to the private dining room though would need to leave by 8pm.
I and other guests arrived 15 minutes late at 6:45 owing to traffic and on arrival we were informed again that we would need to leave by 8pm.
For the next 35 minutes no one came to take our order for drinks or food. I had to go upstairs to request a member of staff take our order given we had to vacate soon.

Our order was eventually taken almost 45 minutes after we arrived though most attention was given to other party in the private room. There was a misunderstanding with the order and when I highlighted it to the waitress she blamed me for confusing her. She called her manger who was accusatory. She eventually agreed to remove the extra meal then I asked her to pack up the meal one of my sisters ordered and she refused thinking I was trying to swindle them into taking food I did not order. Before the food was packed she demanded payment and reminded us that it was approaching 8pm. I flagged that we’d had about 30 minutes between order, food arriving and being asked to leave then they charged £20 service. I paid but my sister said she would jot pay full service as we had next to no service.
Unfortunately an overall poor experience.
