A bit of a walk from the BTS station but well worth it. Forget the set lunch menu and stick to the maki rolls.

This is my fifth time here at ISAO and they never disappoint. The quality of service (very friendly staff ) and taste is exceptional. The special California Maki is as heavenly as always. Do try their other signature rolls, such as the Caterpillar roll and Crunchy Roll which are equally outstanding. Keep up the good work!

I went with a couple of friends. The service was quick and polite. The food came quickly. The food was nice, on my table we ordered the Jackie, which are rolls made to look like a caterpillar with a face. The restaurant is quite small downstairs and the tables are close together, being in a touristy area of town as... More

Positive reviews brought us here, but the wait was a little long. Should have called ahead, but they let us have a beer outside while we were waiting. Gave us a chance to look at the cool bamboo main entrance. The place is busy and as someone who eats here a lot said this essentially guarantees fresh fish 🐠. We... More

This place take a bit of walk from BTS skytrain, and packed with customers and long waiting list too. But we got our table within 20 mins so that's not too bad. Foods are not too bad, however me and my friend got bad tummy after the meal. Probably an isolated case. Didnt have much good range of sake, but... More

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.
