The food at H2O definitely deserves a 5 star rating. Everything from apps, salads, entrées and dessert were exceptional. The raw bar items were delicious! Drinks were brought out quickly. Our service was a little slow but definitely worth the wait. Cute, casual atmosphere. Definitely an enjoyable experience. Our waiter did a great job suggesting a dessert we would normally not have chosen. Peanut butter sundae was awesome!!!!! Highly recommend

A great place to go for a date night. The reservation process was super easy on the Open Table app. The hostess and wait staff were very polite, professional and attentive. To start the meal, we ordered shrimp cocktail and a bottle of white wine. After hearing and selecting the night’s special as one of the main choices, I was excited for the main course. The tuna on her plate was perfectly cooked and the steak on mine was tender and was a perfect centerpiece to a well put together dish. We both quickly joined the clean plate club. For desert, the espresso was nice with the rock candy and this paired well with the layered fudge chocolate cake. Overall, a seafood restaurant that delivers time and again.

We visited H2O for the MVP Dining Price Fixe event and loved it! The menu was a great deal and I loved the pairing with the wines, which varied based on what you ordered. We always enjoy the H2O martinis with our meal. It was an extremely busy night and the staff was awesome. This is a great place for special occasions or a date night.

Went for my anniversary and everything was very good! The sushi platter was absolutely delicious and so pretty as well! The chocolate cake we had for dessert was heavenly! We did order a wedge salad for an appetizer to split but I wasn’t crazy about it. It was very plain but my husband devoured it and enjoyed. Our waitress was wonderful and very attentive. We had a great experience. Can’t wait to go back!

The place is very popular and therefore you need to reserve a table in advance. Service here is top notch. You will be escorted to a table and asked to pick up your outerwear. I can say that the order was received quickly.The food was in the restaurant just amazing.left a very good impression about this place so I would recommend it to anyone who wants to have a good time with delicious food.

Really enjoyable seafood restaurant with very high quality drinks and dining. It’s on the pricey side, but you can see where the quality goes. The service was attentive and friendly without being staid. Our waiter was happy to recommend and suggest options without it feeling like we were being forced or pushed in any way. Great cocktails too: the jalapeno Martini is a winner.
