Koya Japan

Very authentic Japanese hot cuisine in London. Udon are outstanding, try different combination until you find your favourite one. Tempura dishes are great, always freshly made, just like the way they are in Japan. Also try the one on special menu on the black board. There is almost always a long queue but we’ll worth the wait! Hopefully they can add more tables.

Authentic, no-frills Japanese cuisine. This isn't your modern "photogenic" bowl of Ramen that you might be used to, but everything is full of flavour and super well prepared. Service is very fast and the chefs hand the food over the counter to you. Super delicious and very reasonably priced. Very small inside but service is so fast you'll be seated in no time.

Disappointing. I found this place on Google and I decided to pay it a visit with a friend given the high number of vegan options. We got there around 9.30 and the restaurant is closing 10. We were told to wait and then, once seated, we were told that most of the items were sold out which was a bit disappointing. We ordered whatever was available and the food was actually ok. Having said that, the customer service was a bit rude and uninterested which is not great given the prices. The lady who served us was very grumpy from the beginning till the end, and they even forgot one of the two drinks we ordered. Overall, negative experience. Decent food but very poor customer service. They seemed to be annoyed that we came half an hour before closing but in that case they could've just told us and we would've found another Japanese restaurant, there's plenty of options nearby. If they decide to take in new customers at that time they should make sure the service is adequate otherwise they should just shut the restaurant and tell people that they are not taking in any more people. I doubt I will be coming back to Koya.

I haven't been in London for 8 years... And my first had to be Koya: it is by far my favorite restaurant in London. The food is so perfectly delicious beyond its seeming simplicity. I had little tears of joy eating the pork belly braised in cider the udons are the best I've had anywhere and I enjoyed so much my lunch that I came back a few hours later for a serving of cold udon with a hot soup if you're visiting London, do not miss this place

Always loved Koya for the most authentic Japanese hot cuisine in town. Udon is their specialty in my opinion, and they serve an especially delicious CURRY udon. It is out of the world. Tempura dishes are also on point, always freshly made, just like the way they are in Japan. There is almost always a long queue, so either go super early or late to avoid long queuing times.

Hearty, flavorful udon. Noodle texture and chewiness was on point. Portions are super generous, so I’d only order sides if I were dining with someone else. Queues can get quite long during peak times I waited 45-60 minutes for dinner. I’d advise going there for lunch on a weekday.

Love Love Love this place! So cozy and the open kitchen and bar style is great for a casual date! Prices are average considering you are in central London and I love to visit in the summer for their cold noodles! I have visited over 10 times and even 3 times in one week. I always get the cold udon and cold sauce or the buta miso but I want to try other dishes next time! The udon is so chewy and scrumptious! Defo recommend.

Worth every minute of waiting time. The spot is a small space with a huge open kitchen and seating around the long counter. Everything is prepared fresh, their udon noddles are perfect for a winter weather. Definitely a recommend, they don’t take reservations, walk in only.Recommended dishesNiku Udon

Hands down favourite place for udon - especially this branch. Broth is fragrant, noodles have a bite, tempura is light yet crunchy. Also they have really nice side dishes. Always a nice, quick but filling lunch.

Loved the ramen so much!! So delicious! Because of the long line waiting outside I ordered a take away and they packed everything so nicely. It also had a description how to mix everything together.
