My wife and I had our first wedding anniversary and the night was perfect. Our server Steve(n) was great and providing exceptional service. If managers read these reviews then give that guy a raise because we will return for the food and his service.

I would not consider this fine dining by any measure. Service was inconsistent and uneven (requests were consistently forgotten), the food was lackluster (especially for the price point), and the men’s bathroom lacks privacy. At this price point, I would expect the bathroom to at least have a divider between the sink and facilities. My experience was reminiscent of a bar.

I wish the restaurant all the best, but would highly encourage management to re-evaluate.

Everything was wonderful from the moment we arrived until the moment we left. They are attentive, precise, courteous, well informed of their menu and patrons coming into the restaurant. Our food was superb and my husband's bday 50th was wonderful. The dessert and gift card given as a courtesy is just the cherry on top. Love this organization and will be back with pleasure. Never disappoints. Thank you H20. Happy New Year.

The $48 steak was not worth it. Chewy, fatty, hard to cut. The waiter was unmasked which made us uncomfortable.Don’t ask if it’s a special occasion if that occasion won’t going to be acknowledged.

We heard about this place from a friend of ours and had been wanting to try it for some time. We went to eat here on a Wednesday, which was perfect as the place wasn't crowded at all. The food selection was great, we never even got to the entree because we ordered so many apps. Oysters and the tuna wonton was amazing., sushi was very good as well. And the lobster and Squash Bisque was delicious. The service was great too, the waitress had mistakenly taken away the oyster tray and we still had two oysters left on there. When we told her she apologized and brought us out 4 more oysters. Definitely will be going back here to dine.

One of the best restaurants Especially my first time at a seafood restaurant. service is excellent and even thought they were almost closing. I was not rushed out of there and the servers were very polite, kind & patient. The food was really good and I loved everything that I tried. The calamari was really really good. The shrimp was also very delicious. My first time trying lobster and i loved it. I took my mom for her birthday the night before and she really enjoyed everything. We also had the H20 Martini and at first you don’t taste the liquor but definitely give a kick after a few sips. Loved it! I can’t wait to go back and take some
Of my other family member. I really had to get an exceptionally good experience to write a review but i just had to because this restaurant deserve it. Thank you to everyone who’s doing beyond more to give good service.

The service was out of this world, he knew when to come and when to stay away. The food was ok, had the tuna and was just ok nothing special. The bread and honey butter made it so much better, bread made a wow!
Thank you for a nice evening and the server made the difference.

Everything is fresh and delicious. The service was very good and attentive. The menu was a bit small for regular dinner items, but what we ordered was delicious and there is a nice selection of sushi too. Be sure to make a reservation at this busy, vibrant restaurant.
