Yes, it says it is fusion Japanese. But if you think about the definition of fusion, it is just about any rice roll that could be considered as 'fusion'. I went there at 5.45pm and it was already crowded. You would have to put your name down with the number of pax and sit outside to wait. I was 1... More

This is one of my favourite restaurants in Bangkok. The food is amazing, definitely the best Sushi I have ever eaten in my life. The wait for a table is insanely long , but the food is well worth it. It is quite expensive though but worth it. Will keep coming back

This is a highly recommended place to eat if you are around. Service is fast, people eat and go so the wait is bearable, but you don't have to rush, you can still able to enjoy your food and take your time. My favorite food is the sushi sandwich with spicy tuna, it looks very beautiful and appetizing, when you... More

For food and taste would have given 5, but hygiene concern reduces it. Place is obviously popular and they don't take bookings so you have to queue up outside. Now this is where the issue was, they served us alcohol outside in sitting area however there were cockroaches running around on the floor. People were jumping and running but management... More

Absolutely outstanding, we had to wait having not booked, but hay the wait was well worth it even if we were sat at the bar overlooking the chefs. The food is of a very high standard, in fact almost the best i've eaten so far, the only problem is one gets a little carried away and orders more than one... More

This place is a must visit if ur into Japanese Food. Great sushi and sushi rolls. It's quite popular and you probably have to wait to get a table at this small joint. Good quality and very good food. Really worth a visit. Highly recommend.

Staying in Sukhumvit

Neighbourhood Profile
With a mix of shopping malls, hip bars and food stalls lining both sides of Thailand’s longest road, you’ll rarely encounter a dull moment along Sukhumvit. While the main road itself doesn't offer a lot in terms of entertainment, it's the adjoining 'sois' (alleys) where the magic happens. Popular spots are soi 11 for a lively night out, soi 4 for naughty nightlife and soi 21 for world-class shopping at Terminal 21. It's hard to cover everything this area has to offer in on day, so be sure to take your time. Sukhumvit is heavily congested with traffic during day and night, so getting from A to B is most convenient using the BTS Skytrain right above it.
