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.

Very disappointed with the service, food, and the over all experience at H2O in East Islip. I expected a lot more coming from the Bolsen Group.

We have been coming here for quite a while. The food is always excellent! This last visit was not so good as service was extremely slow and a few mistakes were made by the server. They didn’t even give us our doggy bag so I didn’t bother to ask. We were very disappointed to say the least. A diner has better service.

Came here for New Year's Eve. The 4 course meal was such a good price I couldn't pass up on it. The food was well worth the money. I'm coming back here again for another dinner

I came here for NYE and I was very disappointed with the rushed service and quality of food. Typically I’m impressed with both the service and food here but I should have known better than to go out to a priced fixed meal. I would have thought the experience at a Bolson Group restaurant would be superb but it was not. It was disappointing

Food was very good. Service was not great. Bussers kept trying to take our plates when we weren’t finished. They also served our main meal while we were still eating our appetizer.
The best service I had was when I first got there at the bar. The bartender was wonderful.

H20 is truly a gem in E. Islip. The Boehlsen restaurant group has done it again. Enjoy coming for happy hour or dinner with friends. Always top notch.

Our overall assessment of our dining experience is somewhat below average.
The interior design and finish is nicely done and contemporary keeping with an upbeat vibe.
The service is excellent and in keeping with a good Manhattan dining experience. My dinner did nor appear or taste fresh. We ordered your stuffed flounder with scallops and crabmeat. The fish was dried out and the stuffing featured bread crumbs. Not a good value for the dollar. Salads were good and apps as well but very small in portion for the apps. From our observations to sit at the bar and order sushi and a cocktail would be the way to go.

Everyone was very polite and attentive. Went for a Birthday dinner, waitress was very personable. I had questions on the wine list and she quickly had someone come over to explain the menu and even offered me some tastings. Food was amazing with great flavor depths, plus the service was quick. The chef even came out to say Happy Birthday. Highly recommended for a great dining experience!

I have eaten here in the past and the food was great. Monday is lobster night but the lobster was dry and over cooked. The was ,bread tasteless and the stuffing was just unseasoned. It bothers me to spend money and not enjoy my experience. Not impressed with food at all.

H2O was an unexpected delight! We made a reservation with another couple to try out their Anniversary Dinner Menu. The selections were very appealing and we had a difficult time settling on our choices. And the wine tastings that went along with the menu were varied and all that we tried were very good. Our server, Ashley, was very attentive, knowledgeable and efficient. Her recommendations were spot on! All four of us were absolutely pleased with the experience. We will be back.

Everything was "acceptable " but not excellent. I made a reservation in the morning for 7 PM and they gave us the last seat in the back by the door! The waitress came over to ask various questions multiple times and interrupted our conversation a lot. The food was okay. I didn't want to take home what we didn't finish so that tells a lot.

We frequently overlook H2O which is around the block from us when trying to decide where to eat out., but will ensure this gets put back in the rotation. Ate here on a Friday night, train was delayed so we were 15 minutes late, no issues being seated. Great cocktails and attentive service. Had the cajun dusted shrimp which tasted great but could have used more heat for my taste. Overall a lovely place for date night.

Food and Service was amazing. Ashley, our server, was very sweet & never missed a beat. Hopefully, you're as lucky as we were to have her when you dine there. Sandra stopped by our table and was very accommodating to our requests. The dining setup was odd but overall we had a great dining experience.
