The best restaurants serving Japanese food in London

This place is a well kept secret! Best ramen I ever had at very reasonable prices!

I ordered takeaway, and the food was inedible. The chicken tasted off, and the noodles were nothing more than overcooked spaghetti. On top of that, look at the condition of the mochi when it arrived! Extremely disappointing, especially considering how much I paid. Such a shame.

So I actually just got back to London after spending 2 weeks in Japan, and I must say, this is the best Kosher sushi I have tasted in the world, even compared to some of the best sushi restaurants in Japan, this sushi is the absolute best. From the presentation, freshness and quality of the ingredients, the service, the politeness of the staff and the atmosphere, this is the best Kosher sushi restaurant I’ve ever eaten at.

I went to ITSU 5th December 2024 for the first time. I really enjoyed my visit. The food tasted delicious. The food was fresh and healthy. The machines were easy to use. The customer service was amazing. The free soup I was given was really tasty too. The staff asked if I needed any help and they were friendly. The place was clean and tidy,

nice place, nice food and friendly staff and super quick service

We ordered chicken gyozas and ramen and they were spectacular. One of the best we have tried, the noodles are incredible and have a great flavor. The restaurant is quite small, so make a reservation if you can. A great experience.

Absolutely splendid sushi at a really good price, very friendly staff and good atmosphere.

Tasty but tiny portions, the amount of rice is ridiculously small. Quite overpriced.

Overall a happy experience with my family of 4, with 2 kids. Just the first waiter who serves us didn't bring the set dinner menu that should be available on Sunday night. We asked him for tap water but he brought us a bottle of still water. It seems that he was trying to get as much money out of the customers' pocket as possible. From ordering to finishing, we tried to avoid this specific waiter. The other waiters are nice and friendly. Food can't be said top-notch but I think it is acceptable given the central location and atmosphere.

Love this place, come to visit virtually every time I come to London. Great food and service, and lots of reasonably priced Japanese fresh produce and items like cutlery, bowls, cups, etc 😊 Highly recommend!

Great service, great quality and flavour of the dishes.

Quiet place with fast service. Nice food too!

We had a really good time, the venue felt safe with good amendments for social distancing. The food was good too. Not cheap but good value

This was, without a doubt, the worst service experience I’ve ever had. From the moment we walked in, no one greeted us, no smile, no “hello,” not even basic eye contact from any of the staff. The atmosphere felt cold and entirely impersonal. The lack of hospitality made us so uncomfortable that we left before even placing an order. The staff’s behavior was unwelcoming, rude, and careless, making it clear they had no interest in providing good service. When we left, none of the staff bothered asking why we were leaving! It’s evident that management is failing to foster a positive or cohesive work environment. There was no sense of coordination or understanding among the team. I feel like they couldn’t care less of their job, no motivation at all which could explain the overall lack of morale and miserable attitudes.

Don’t accept the small tables in the middle, as you will end up guessing what you're eating.
