Seafood
Opened in 2016, H2O Seafood & Sushi in E Islip brings our signature seasonal seafood to the South Shore. The sea dictates what’s on the menu at H20, as, whenever possible, our Chef sources local fish and supports local farmers through creative takes in the kitchen. Grab a seat at the expansive gray marble bar while tasting startlingly fresh sushi or our modern American seafood classics. The sprawling menu features treats from the ocean, fresh Bluefin Tuna, Scottish Salmon and also satisfies land lovers with dishes like our flat iron steak with Sriracha butter or our pan roasted chicken with cornbread stuffing. Shareable desserts like the donuts with coffee pot du crème make indulging almost impossible to avoid. Cleverly designed with an upscale New England feel, you’ll feel like home in this warm and inviting space.

Dinner was very good. However the daily special,while tasted good, used shrimp that were disappointingly small. For a$30+ ala carte entree, the value just wasn't there.

Food was excellent. Unexpectedly in a seafood restaurant, the steak was wonderful. Service was attentive but unobtrusive. Great experience.

We have been here several times - with and without friends - always a great dining experience. Food is prepared as requested and the service is always excellent. Nice happy hour prices at the bar and weekly specials. Menu appeals to both sea and land lovers.

Very overpriced below average seafood. My wife had fish tacos. $21.00 for 3 tacos with a few pieces of cod in it (which where supposed to be blackened but were not). I had sushi. To be honest, I have had better sushi at a supermarket. I felt like I was eating in a diner but paying high end restaurant prices. What a disappointment. Will never go back.

We truly enjoyed the Restaurant Week dinner selections. Our server was wonderful -- so attentive and helpful! The popovers were a lovely treat with the honey butter and our fish selections for the main course were melt in your mouth delicious. The maple vinaigrette was a delightful compliment to the salad.

The Tuna was very good, but the stuffed flounder was dry, and really a stuffed flounder rollatini, not the traditional flounder with a pile of crab meat stuffing. The watermelon margarita was excellent

Everything runs like clockwork at H2O - good specials, reliable value, quick service. My only complaint, and I hesitate to say this, is that we were repeatedly interrupted by the manager and server asking if everything was ok!

We were very disappointed with our meal last Wednesday. We ordered the wine and dine menu and the lobster was terrible. It was one quarter the size of a small lobster and it was dry. I can't believe this is a seafood restaurant. The appetizer was fine. We regularly dine at H2O but this may have been our last time. We all left feeling hungry.

Sunday Surf and Turf special for two at $68 is an excellent value, especially as it’s $90 the rest of the time. Well prepared and nicely served. I’ll be back.

We had the salmon as part of the wine and dine menu and it was absolutely the best we have ever had! Our waitress, Erica was fantastic. She spaced out the courses so we were able to enjoy the wine and she always stopped by the table to see how everything was going. The upside down apple cake was excellent!
