I already wrote a long extensive and detailed summary to H20 explaining a play by play regarding the awful experience we had at this restaurant. I will say again we eat at the other partner restaurants in the group and always enjoy them but even our friends warned us they H2O was the worst of them all and sure enough they were spot on. We have family who lives down the block who also said they went once and wouldn’t go back and that’s obviously sad since the place is off the road where they live. So that speaks volumes with how crappy of an experience they even had. This place is like the u wanted child of the group and it’s blatantly obvious. I am not going to write an entire review again but basically it was garbage and the only reason we went was the $40 gift card that came in the mail. So the one plus you can take from it is your promotional vehicle worked but you didn’t have the product or service to make us come back

Had a craving for mussels and french fries so went to H2O with my wife. It was so-so, a bit of a disappointment. The place was pretty quiet on a Sunday night, so we expected more from the service. Waitress was inattentive, not helpful, passed the menu and only mentioned the daily specials because we asked. She was later quite impolite when she questioned the fact that we never heard of bronzini. Appetizers were good (spicy yellowtail rolls, crispy calamari), the classic mussels and moules frites were adequate but lacking in flavor, the vanilla creme brulee was good but the warm chocolate skillet cake was overly sweet. The Gabriella Pinot Grigio was an excellent choice and the Brooklyn Lager did not disappoint. In the end it was a very mixed experience. Not sure we will be back.

My wife and I frequent your Smithtown location and appreciate the consistency of your food. We figured we would give your East Islip location a try. The reason for the 3 star overall experience is the two bar style tables you have in the back of the restaurant where there certainly shouldn't be any tables, by far the worst two tables in your establishment. Make more room for two tops or get rid of those two tables. Was shocked that I was sat there, the tables are small and up against your booths, I was able to watch what the booth next to me was eating, not exactly the view I wanted for my Saturday evening out.

I took my boyfriend out for his birthday and the food and service was absolutely amazing. We got the octopus and lobster sushi roll for an appetizer. For the entree I got the Mahi special and my boyfriend did the filet Wellington. Easily one of the best meals I’ve ever had - for both of us! Waiter was awesome and very nice and the owner/manager came around to speak with us afterwards and gave my boyfriend a gift card for his birthday. Will definitely come back, the place is really great. Thank you!

We were celebrating our Anniversary Saturday and wanted to try H2O. We knew from the website what we wanted. The NE Clam Chowder with Bacon was excellent. Also the Clams Casino. They were crunchy on top and clam cooked well. My wife was very happy with her Lobster as it was de-shelled for her too.
And the Mashed Potatoes were so buttery and creamy. We both ate that. My Sea Bass was crunchy on top and flaky. It melted in my mouth. Sauce wax great too. As for drinks, the Tellers Old Fashioned was excellent. And my wife loved the H2O Martini, she had a second and convinced me to switch to it after my Old Fashioned. Our waitress was really great too. All in all, a great night. We'd return

Service at the table was good and the food was decent but not fantastic like it usually is at the Smithtown location. Was seated a half hour late after our reservation time and was only offered water. Should have been offered a free drink for the wait time.

Went here for Valentine's day under an Open Table reservation. Dinner was a set menu of choices @ $59 per person that included choice of 1 appetizer each, 1 entree each, and a shared dessert.

Good:
1. Excellent Service and friendly staff.
2. Great bar cocktails (H20 Martini & Regular Mojito).
3. Appetizers were very good (H2O Roll and Rock Shrimp). The Rock Shrimp was bigger than expected so that was a plus.
4. Dessert: Red Velvet cake was very tasty.

Bad:
1. We were seated in the bar area were it was very noisy, kind of cold, . We were asked if we were ok with this, but we were also told if we didn't we would be waiting a while. We had to provide credit card for our reservation and would have paid a penalty if we didn't show, but we did show and we're not given a regular table for our time slot.
2. Entrees were ok (Swordfish & Boston Lobster Roll) The swordfish was kind of bland and the lobster roll was a disappointment because the roll was soggy and the amount of lobster was lacking. It really was just chunks of lobster with some mayo dabs. I've been to Boston and they don't look like this.
3. Dessert: Chocolate covered strawberries were borderline edible. The strawberries are very fresh and tasty, but the chocolate was awful tasting.

Overall I might give this place a try again if I'm in the area, but I don't think I would ever return for another holiday event.

Always go early for us at about 5pm so the noise level is not energetic. Greeted properly. Went in 15 minute before arrival bar 4 pm. Went to the bar and had a couple of drinks with my wife. Beautiful comfortable atmosphere. When seated our waiter, Patrick went above and beyond our expectations.So attentive. I’m bias as I’ve been a waitress in the past, Patrick was exceptional and such an asset to your company. Food excellent

We went in with a $40 off $100 card from Bolson...
I had never been, and was not disappointed.
The Service was great from the hostess to the waiter and the wine steward. In fact, a terrific red wine was recommended for us to pair with our meal.
They have daily specials that are reasonable, so I will be returning.
