    Although the noise level was high.... My eating experience at H20 was fabulous. The staff was friendly and accommodating ( even the valets!) our server was knowledgable about the food and drink, and the atmosphere was inviting. Some items on the menu were a bit pricey for no reason (a grilled shrimp dinner with 5 large shrimp .....34 dollars?!) however was cooked to perfection as was everything else. A definite keeper!

    I just moved to long island and I must say, H2O really impressed me. I've heard really good things about it as well. I had the dragon sushi which I happen to not like because it was warm sushi (not the restaurants fault) the manager came right away to see if everything was okay and if I wanted to replace it with something else. I decided to get the rainbow sushi which is absolutely delicious and the manager got it done right away. Talk about rgrat customer service. I'm very please and do recommend this restaurant! P.S- Pineapple mojitos are amazing as well!!

    Long island has very few good seafood restaurants. This is one of them! The fish was fresh and beautifully prepared, our waiter was well informed and willing to accommodate. The only thing given how packed the place gets service was on the slow side. Will be going back again and again!

    We had a business dinner at H2O. It was restaurant week and the dining room was quite busy, though the service was still excellent. I was the local and the rest were from London, New Zealand and Texas. To a man, they really enjoyed the meal and the ambiance. One person did not eat fish and he had one of the steaks on the special menu and was thrilled with it. The rest of us had sushi as an appetizer and fish for the main. We were all pleased with our choices. It was a successful dinner!

    We have been going here for years and we have noticed it has been going down hill but this last time definitely sealed the deal. The food is still pretty decent HOWEVER the drinks. It's horrendous! My margarita was water with salt on it. My husband ordered a watermelon martini that was also tasteless and he even tried a espresso martini, another disaster. We finally went with wine just to play it safe. For the amount of money that is spent that is just not acceptable.

    The manager made every effort to accomodate our tight schedule, and for this we have to thank her. The food was good, but not outstanding. The clam chowder with bacon is very tasty -- little clam, lots of corn and bacon flavor satisfying. The Montauk Roll is good, but mushy mixture of different seafood with spicy sauce. Texture not great -- only tuna has some body in this roll. The lobster wontons were reminiscent of pizza in texture -- too bready though tasty. The etouffée was a mélange of foods that failed to come together as one dish, but was a good entree. Overall, we were expecting too much of H20 which curiously enough lacks a water view unlike its sister restaurant Prime (on the water), whose food and view we prefer.

    We went to H2O on a Wednesday night. We were excited about their Wed. Night Wine dinner but there was only one entree selection and it was for steak ... odd for a seafood restaurant. That was disappointing. However, our meal was good. The Salad with apples, walnuts and goat cheese was ordinary, as was the bronzino and grilled swordfish. Not as good as the last time we went - perhaps we made the wrong choices.

    We went to H2O for a Price Fix menu to try it. I was very surprised on the quality and nice size portions served. Apps and main dishes were wonderful. Dessert was bread pudding which was good for what it was but I would have like a few more choices in this course. Our server was wonderful as well as the assistants. My water glass was always full and even though it is a small thing it is one of the specific things I rate my experience by.

  • First Taste of Fall 2014

    Dined on 9/26/2014
    We took advantage of the promotion for "First Taste of Fall" and were not disappointed. Making the reservation through Open Table was easy and seamless and our dinner was excellent. The marinated skirt steak was cooked and seasoned perfectly, the swordfish was as well and the scallops with pumpkin risotto was the talk of the table. The only drawback was there were only 3 scallops on the plate. Everyone enjoyed their meals thoroughly. Two of our group also added the "wine pairing", and the wines were very good and the amount poured was equivalent to what you would expect if just ordering a glass of wine. We had a great time, enjoyed everything and definitely recommend you give them a try.

    Dined on 9/26/2014
    On average, we eat at H2O every 18 months. Over the past few years, the quality of food and service has been consistently excellent and this latest experience proved to be no exception. We ordered off the fall prix fixe menu and particularly enjoyed the kale salad and the marinated skirt steak. Service was perfectly pitched - attentive and friendly but not pushy - despite being very busy. We have never been disappointed at H2O - it deserves more frequent patronage than we are currently able to provide.

    Absolutely one of the best wine programs on Long Island. They offer a very thoughtfully curated selection of boutique wines at tremendous value. They offer a wine and food pairing menu on Wednesdays for guests as well. The restaurant was recently given a refresh and looks great. The bar has lots of energy and the service in the dining room and the bar is excellent.
