This was my first visit to H2O and it will not be my last. For my starter I had the H2O Roll. I figured if it was their namesake it must be excellent. I figured correctly. The roll consisted of Shrimp Tempura, Spicy Tuna, Cucumber, Eel Sauce and Spicy Mayo. This combination works wonderfully and also was presented on the... More

A recent visit to H2O proved that fine seafood is available on Long Island without going to Montauk! We especially liked the casual ambiance at H2O along with the superb selection of fresh seafood. The tuna proved to be superb - I had it blackened, rare with wasabi. It was close to the most exquisite sushi grade tuna I've had... More

While the service was a bit slow (and the restaurant wasn't very full) you can't go wrong with the food. Top quality, delicious and don't miss out on the Japanese Cowboy roll!

I met some neighbors for dinner. This is a good gathering place for friends, family, couples etc. This is a good restaurant. I had the swordfish. It was very fresh. We all enjoyed our food

My husband and I went here for the first time on New Year's Eve. We did not participate in the price-fixed menu option so we ordered off the regular menu. The atmosphere inside is very nice and upscale but the menu threw me off as they have a sushi section and sushi appetizers as well as a regular appetizer section... More

I went in search of a good seafood restaurant west of the East End. My trip advisor search led me here. Nice spot part of the Bolson group that owns Verace and Tellers, both excellent restaurants. Very good service and atmosphere. Very expensive sushi offerings, and a short cooked menu. We had the Crusted Tuna which was very good, crusted... More

Seafood i had was bland, but the sushi was pretty good the bar makes a good well balanced drink. Overall was just ok for the price. I went for my anniversary with my wife still a nice evening with an upscale atmosphere. I cant speak for anyone else but im still on the lookout for good seafood on long island.

We stopped at this restaurant for dinner almost by accident on a busy Friday night, and had no great expectations. However we found the service excellent and the seafood was beautifully prepared and well-presented. The wine list was straightforward and very reasonably priced. The dining room is large, attractive, and not too noisy. On the night we were there a... More

We eat fairly regularly at H2O. The food and service are consistently good while the modern nautical-themed decor works well (and the noise level is low allowing for conversation). While we have eaten there a number of times on weekends, our usual strategy is to view the weekly email for the fixed Wednesday night wine dinner. This three course meal... More
