    We have been coming here for years and always look forward to our meal. Food is delicious and nicely presented, staff attentive. Lots of booths in the dining room so that even when the restaurant is very busy we can talk to each other. Highly recommend.

    I recently went to H20 to over the weekend to celebrate a birthday and attend their restaurant week event that included a special price fixed menu, which was extremely reasonable, and had the option to include unlimited wine for $10 per person, such a great deal. The menu had excellent options for each of the three courses, that my party of 3 all loved each course as we all tried different combos -- everyone was MORE than satisfied with the food (the salmon entree was to die for!) along with the friendly and helpful service. The atmosphere is great too with nice decor and it had a very lively crowd on a friday night (you might want to make reservations). The coolest part of the night, was that the staff acknowledged our birthday girl (and spared her the embarrassing sing-a-long at some restaurants) and sent us home with a gift card to use towards dinner next time. Thank you H20 for a wonderful night, we'll be back soon!

    Recently went there again for LI Restaurant week. This place is just so creative, but not in an over-top way where the food becomes unappetizing. All menu selections are unique, not something you'd see anywhere else, and the seafood and sushi tastes notably fresh. For my entree, I had U8 shrimp , which was dusted in "Angry" flower and served with a millenium pan sauce; a perfect balance of spicy, citrusy, and sweet. These U8 shrimp were HUGE- like small lobster tails, and remarkably tender and cooked perfectly. The LIRW menu at h20 was much better than other comparable restaurants. The wine pairings were perfect and added to each course, the portions were perfectly sized, service was impeccable. Will be back again and again!

    We order food from the Restaurant Week menu. Ok, let start off with the appetizer. Crab cake; good. Sushi; Good. The Branzino looked like a filet of sole from the bottom of my fiance boot . Branzino is a whole fish that is supposed to be filet in front of you, served with the head. The shrimp was extremely dry and over cooked. The beer list was just awful. Bar was cool. It was very loud while you ate. On a good note, the waitress we had was very friendly and helpful. Ive been going to this restaurant when it first open. The food was delicious and fresh. I have not been there in over 5years. I was extremely disappointed

    The sushi rolls were rolled very loose and poorly, my boyfriend had a piece of bloodline in his sushi roll. The popovers were very dense, seams as if the batter was over beaten or not enough leavening was put into the batter. My boyfriends shrimp were over cooked and rubbery while my veggies under my steak were so charred they were black. I've eaten at H20 before and haven't had a terrible food experience quite like the one above but the food at times has been under seasoned and the taste certainly does not parallel the high prices.

    We were there for restaurant week. The food was excellent. Our meals were well prepared. The service was very good as well. Although probably because of Restaurant Week, it may have been a little rushed as we were in and out after three courses in just under than an hour. The only interesting we noticed was after the soup was served and taken away and before the entree was served, our server made a special trip to our table to pick up our unused packages of oysterettes. I thought that was interesting in that they don't even do that at our local diner. BOTTOM LINE- we will return and weven would recommend this restaurant with the cautionary note that it is expensive when there is no restaurant week.

    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!!

    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.

    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.
