Excellent authentic Japanese. Brilliant atmosphere.

This was our fifth time to visit Koji, every time we visit London, we always make a trip to Koji. Starting with the amazing ambience- perfect for a romantic date or a group of friends/family. The sushi is one of the best I’ve ever had, anywhere in the world! And they have an amazing selection of cocktails. Waiters and staff are so welcoming and helpful. A very special restaurant.

The wine list is priced outrageously which is why the overall rating is low

The food was amazing and very high quality.
We enjoyed every bite!

Fantastic service and the best tempura I’ve had in some time!

Great food great service as usual

This was somewhat of a random find but the food was excellent. Great service and friendly, very attentive. The food came out quickly and hot and was surprisingly delicious.

Very good as usual

Absolutely delicious meal for my boyfriends birthday. Service was outstanding, waiter was able to tell us where is type of fish was sourced from. Really recommend the crispy rice with spicy tuna, black cod, scallops with truffle and seabass sashimi salad. Rock shrimp tempura was cooked to perfection. Very similar to Nobu and great to have so locally instead of going into the city!! Very happy customer. Not cheap but perfect for special occasions.

Excellent cocktails & great food. A little too noisy & slightly chaotic service but overall a great place albeit pricey

Delicious food and excellent cocktails, but very aggressive prices (£15+ per cocktail). Rather empty at lunchtime on Saturday so slightly lacking atmosphere. Staff are very nice.

Good food, but very slow (although kind) service and expensive. A full dinner for 2 with wine and dessert will set you back £150

Superb Food, superb cocktails, great vibe...100% Positive

Food was great. Music was reasonably good and not too loud so could converse. Their non-alcoholic cocktails selection looked great and the ones we tried were excellent. Definitely recommend checking it out.

Appalling food quality. Fish was itsu level at best.

Wonderful food, beautifully served, a feast for the eyes and the taste buds, delightful evening with friends but very expensive !

a little bit expensive i would say

Exquisite cuisine and great service in a beautifully designed asian fusion atmosphere

Very good Asian / Japanese inspired food, perfect service - highly recommended.

Fantastic food and wine would definitely recommend

This is second time I’ve been here however I love it. The cocktails are fantastic with a big selection. The staff are helpful especially Tulip who was taking our drinks orders and making excellent selections. Would definitely recommend the amaretto sours.

Food is exquisite. Sushi table is a great touch if your inquisitive!

The food at Koji was all good quality with a few inventive dishes, but the menu is a mess - almost impossible to navigate, too many options, poor guidance from the waiter and no idea how much food your going to get. On top of that it is far too expensive for a local restaurant. I think the owner has ideas above his station. Good food but bad experience and too expensive.

We were in 7 and the waiter suggested us the wrong thing. Each of us left the table starving and payed £43!! Maybe in two people is a different experience. If you are a big group don't order the big sashimi/sushi plates for £65, go for a plate for each of you.

Excellent food but too expensive and also acoustics poor so difficult to hear on a table for 4!
As much as food is very good I think if they continue with the high costs for the food and drinks then they are likely to not have a significant repeat business.

Excellent food but high prices. Big menu for food and drinks. Creative and lively. A great date spot!

Delicious food brought to us with a smile. Rock and Roe was amazing, had two go for a second portion

Great evening, delicious food delivered by excellent friendly waiters, amazing cocktails and desserts. A really fun and vibrant atmosphere I will definitely recommend it, it is on the pricey end but absolutely worth it

Could have had prosecco as opposed to only champagne. Black cod of mini and E&O quality, exceptionally good but perhaps too much expensive in general. Choices for children good and chicken wings skewers made the evening!

Food was outstanding! Would recommend ordering between 7-8 dishes between two - appetisers and maybe a main dish each. Would definitely recommend this restaurant. Perfect for a birthday or special occasion.

Cool atmosphere, great food, attentive staff... this is going to be our favourite local!!

Very good sake it's a shame that food it wasn't that great!

Food is delicious, cocktails are amazing - but it is expensive.

Have been to Koji several times now. Food was fantastic as always and service was attentive without being overbearing.

A neighbourhood restaurant charging Mayfair prices. We were very surprised at what poor value for money it was - really expensive for what is only average food. Cocktails were £15, which is a joke??
It's a nice neighbourhood restaurant, nice food and nice ambience - but unfortunately the prices will put me off returning as it's just too expensive for a good venue for friends get-together.

After my daughter went here for a friend's 18th she didn't stop trying to persuade us to go and take her and other family members. It certainly lived up to the hype as the food was really exceptionally good.

Honestly, stumbled upon Koji as was visiting family in London and wanted something a little different in a specific area. Am now a huge fan and will recommend Koji to anyone who asks for a great place to dine. The ambiance, service and food was an absolute treat which struck the balance between food and formality perfectly. Great first experience and definitely won’t be the last, thank you for a lovely evening

Very expensive but we love this restaurant. Beautiful setting, amazing service and Nobu quality sushi right in our neighbourhood.

The service was absolutely impeccable and discreet - 5* attention to detail, lovely lighting too. A real hidden gem.
We went for my father’s birthday and he hasn’t stopped talking about how great Koji is!
Interesting flavoursome dishes. I’m latina and very familiar with Peruvian cuisine, I also love sushi, and couldn’t fault any of the dishes. There were so many more I wanted to try after having taken my first bite! Thank you to the Koji team for making it an unforgettable birthday celebration. We can’t wait to come back!

Good food but way too expensive : 180 gbp for 2 people without alcohol.

Good food but way too expensive for what it is. We spent £220 for two people and only had 2 cocktails each. Both drinks and food are ££££
