This is one excellent eating experience. Everyone who works there including the bar staff, the wait staff, the assistant manager and the restaurants owner showed a caring attitude and made sure our experience in the restaurant was memorable. We ate at a leisurely pace: the waiter asked at several points if we were ready for the next course which puts... More

When I called this afternoon to make a reservation, the gentleman that took our reservation was so welcoming and I found out during dinner that he was the manager, his staff is as attentive & gracious as he is. Food was delicious , from the pop overs w/ sea salt butter right thru to dessert (which was on the house,... More

We hadn't been there in a year or so. we out for dinner on a Monday and because most restaurants in the area are closed we decided on H2O. I had forgotten how good the food was. I had lobster bisque for an appetizer and stuffed sole for an entree. The food was perfect. The waiter was attentive and polite... More

I went back to this restaurant after not having been there for several years. Just never thought of it when we were looking for a place to have a nice dinner. Well, the service, food and atmosphere were just terrific. We were two couples and all of us enjoyed the meal. The booths are comfy and allow for a little... More

My family group of 8 people ate here Saturday to celebrate my nephew's birthday. From the minute we walked in, we were treated wonderfully by very friendly staff. We made reservations that day and the only thing available was in the "lounge" which is their bar. We were very comfortable because our table was on the side, but it did... More

We usually sit in the bar area and enjoy the happy hour and then a nice meal. The staff is always pleasant and food well prepared and delicious every time.

Sat outside with some friends. Waitstaff let us stay as long as we wanted without bothering us. Popover bread they give you is delicious. We shared some apps and the seafood paella which was more than enough and was loaded with the good stuff (lobster tail, crab legs, etc). My only complaint is I wish the menu was a little... More

We went with out-of- town relatives to celebrate 2 birthdays. We have been to H20 twice and my father-in-law wanted to go there for his birthday. The out-of-towners and my father in law had the swordfush - which they loved. My daugher in law and I had 2 rolls - one of which (the volcano) was good. The other two... More

On a girls night out, service was terrible, very slow. Between a waiter/bus boy spilling a plate of soy sauce over me, then having them remove the stain in front of everyone, then the manager came to apologize, giving me a $25 gift card for a future visit, which I tried to use a month later, but was told there...
