The best restaurants serving Japanese food in London

They are very amicable with lovely foods.

This is such a great spot for dinner. My husband and I go here at least once a fortnight. The soups are to die for! The staff are fantastic too. Would highly recommend!

I agree mostly with the other reviews.. Atmosphere and staff really good. Food is OK though not authentic Japanese (in fact no Japanese chef or staff working here as far as I could see) and definitely too pricey for what it is.

The food is decent but the staff aren’t very nice - they kept pushing us to leave because there were people waiting for tables.

Proper Izakaya in a great spot. Really enjoyed. They have whisky high ball and chu-hi which is pretty rare in this city

Best Itsu in London. Lovely management team and staff.

Ordered salmon don and chicken katsu curry for delivery. Salmon don doesn't look great compared to images or website but it's barely passable I guess. Chicken katsu curry has barely anything in it, chicken looks sad and depressed. Do not order this. A shame as reviews for this place look good but it seems they don't uphold nearly the same quality for delivery so do bear that in mind. For the price you're paying I do not recommend.

The place is perfect for any business or otherwise high value meetings.

This is a really cosy place, would be lovely for a date. Popped in while travelling for work and was so well looked after. Nothing was too much trouble, and the food was amazing.

Ippudo Ramen has lost its charm. While the broth remains rich, the portions have shrunk, and the toppings lack freshness. The biggest letdown was the service—once attentive, it's now slow and disinterested. For the high price, the overall experience doesn’t deliver the value it used to. Sadly, Ippudo no longer justifies its premium cost.

The crazy crunch vegan and chicken were fab

Today was an absolutely dreadful experience. I arrived with plenty of time, only to be told I could have the table for just one hour—a statement that immediately made me feel unwelcome. It was insulting, as if my presence was an inconvenience. After my order was taken, I waited over half an hour, watching people who arrived much later than me being served their food first. When I finally complained, they promised my sushi would arrive in five minutes. Fifteen minutes later, still nothing. I repeatedly asked to pay for my drink so I could leave, as I was furious and running late for an evening event I had carefully planned. I didn’t have the luxury of extending my time. After much frustration, they finally let me pay, but by then my patience was gone. As I stormed out bitterly, having received no food, I walked past the open bar and saw, to my utter disbelief, that they were only halfway through preparing the sushi I had ordered 50 minutes ago. This was an absolute failure—either due to appalling management or severe understaffing on a busy Friday night. They completely ruined my evening! I cannot fathom how such incompetence is allowed to persist.

I’ve visited Wagamama several times, and the consistent highlight of my experience has been the exceptional service from Sahan. Every time, Sahan goes above and beyond to ensure that guests feel welcome and well taken care of. His attentiveness, professionalism, and warm demeanor truly elevate the dining experience.

One of the best Japanese restaurants I’ve been to in London. It’s never easy to successfully add a twist to such an established cuisine, but these guys have figured out a way to do it for every dish. Will definitely be back.

Food used to be great at Kokoro Putney but something changed a while ago and warm dishes are way too spicy. Especially the sweet chilly chicken used to be one of the best dishes but now is so spicy that is barely edible. It is not sweet chilly anymore but rather just chilly. We hoped it was a one off thing but food quality seems to have dropped.
