My reviews of H2O must be pretty boring by now because all I do is gush about this place!

Angela the General Manager is AWESOME! She treats her guests like they are lifelong friends; she is a gem!

Tim our server took great care of us. Our first time meeting Tim but he was on top of everything, from making sure I had extra water and extra butter to bringing out a special birthday dessert at just the right time for my dining companion. Kudos to Tim!

Always happy to see (Assistant?) Manager Tracy and the hostesses who are always so welcoming and accommodating.

Now, about that delicious food: Great Wine Wednesday Dinner special featuring a yummy scallop and shrimp ceviche, a tasty skirt steak cooked a perfect medium rare, served with seasoned French fries, and a unique third course composed of brie cheese with warm apples, strawberries, and honey drizzled on top. I'd like to try and make that at home!

My dining companion, the birthday girl, had the daily whole fish special which was Branzino served with roasted (?) potatoes and sautéed spinach in a tomato bisque-type sauce. For her b-day dessert the gang brought out a piece of their famous tear drop chocolate cake, which is a layered chocolate-hazelnut mousse, almond sponge cake, chocolate crunch bar, vanilla ice cream. She loved all of it!

And last but not least, even though its what we started with, their popovers are truly to die for! I could eat four of them all by myself, but I stopped at just two...and a half :)

Thanks for reading!

Visited to take advantage of their Monday Lobster Special. Tim was our server and he gave outstanding service. We each had a two pound lobster which was cooked to perfection and was delicious.

We will be visiting again to take advantage of this special.

Celebrated Grandma’s birthday. It was lovely. First we were seated by the bar which was too noisy for Grandma but the staff was very accommodating and set up a booth for us further back. Fit 5 Adults no problem. Drinks were great , I highly recommend the Babylon Express. The menu varied from fish tacos to beef Wellington. Both were delicious. The staff was very friendly and gave us a free dessert for the Birthday girl. She also received a $25 gift card to come back again- which we will! This is our third time eating here and it never disappoints. This place is fresh and light inside and was great for a summer birthday celebration.

The sushi/sashimi platter for two was tasty, great value and plentiful. My husband enjoyed the H2O martini. The restaurant is the right blend of casual/dressy. You can wear anything and feel like you’re dressed right.

We had two fish dishes .I had the sea bass over spinach and a potato pancake with a tomato base sauce. It was excellent.
They had a salmon on the menue with wasabi. We asked if they could simply grill it with some spinach. They readily compiled and it was excellent. Service was superior.
If you haven't been in a while it's time to go back!!!

Beautiful restaurant. Well designed and looked promising however, drinks were over iced and food served warm. I’m familiar with H2O in Smithtown and that is a gem but this sister restaurant doesn’t hold a candle to the original restaurant. Service was excellent and the hostess very accommodating but it doesn’t make up for bad drinks and adequate food.

H20 is a great restaurant. The service was and always is very good. Their food? Wow! Their sushi is so fresh. The lobster roll is to die for. The desserts amazing!!! I’ve been there multiple times and have also taken sushi to go. I highly recommend this restaurant. Perfect for families and/or a date with a friend etc.

White wine bottle left on table. Should’ve been out in bucket. Lobster came out wrong and tried to get managers attention but he was watching b-ball with the staff. Lobster served without bowl for shells and warm towel. Came much later.
Just was not up to par with H2O Smithtown. Description didn’t say that this Was more of a luncheon type restaurant.

My husband and I went to H2O East Islip last Friday night for a little date night and it was incredible. Highly recommend for dates or special event dinner. It was a bit pricey but for a special time it was perfect! Looking forward to going again and trying the specials they have during the week.

The interior appeared to be a mixture of new and mid century modern décor. The restaurant stated that diners dress in business casual but the wait staff wore jeans and sneakers. It felt like they remodeled the Beach Tree Restaurant (previous casual dining restaurant) and just reopened at a more expensive level.
The sushi was ok, there are an assortment of local sushi restaurants that far exceed what was prepared at H2O. The wasabi mashed potatoes were too spicy. Service was just adequate. I don't think we'll be returning ; we had heard so many good things about the H2O location in Smithtown but others who have been to both locations say it's very different.

I was very impressed with the food, the service and the selection. We were lucky to be there for restaurant week. The choices were varied and everything sounded delicious. I chose the scallops. They were nicely seared and the caramelized rice was an unexpected delight. My friend ordered the Beef Wellington and enjoyed every bite. I cannot wait for my next visit.

Very disappointed did not meet my high expectations. Stuffed flounder was just bland bread stuffing there was very little flounder and it was very dry. Calamari was greasy and warm not hot. The upstairs chairs are a tacky plastic not what I expect from a high priced seafood restaurant. The upstairs dining room was so loud I felt like I was in a cafeteria. I have been to PRIME, Tellers and Versace and all three are very good and was expecting the same quality at H20 but this restaurant did not deliver.

We were disappointed in our choice to go to H2O for Restaurant Week. The service was poor and unorganized and we didn't think the food was worth the value. I wish we had picked a different place to eat.

service was exceptional...friendly staff...beautiful inside. we went for anniversary which happened to be during restaurant week. Food was good however my appetizer, fried calamari should I say was entertaining? I hate sending food back, bread crumbs were good, but the calamari itself was like plastic, I can't even say chewy. Our 18 mon old grand daughter Chewed 3 pieces over and over and once bounced out of her mouth. she must of loved the flavor. The crispy rice with scallops is that crispy...but over all we really enjoyed ourselves. I would go back and might even give that calamari another chance.
