About this restaurant

Neighborhood gem
Good for special occasions
Great for outdoor dining

Since 2001, H2O Seafood & Sushi has showcased seasonal seafood, served with passion, and conceived with creativity. Designed with an upscale New England feel, you’ll feel right at home at H2O in our warm and inviting space. And what’s on our menu is dictated by what’s in the sea, with our culinary team proudly sourcing local fish and supporting local farmers through their creative takes in the kitchen.

Guests are invited to sit at our expansive gray marble bar while feasting on fresh sushi or our modern American seafood classics. Our delicious menu not only features abundant fish, but also satisfies land lovers with celebrated dishes like filet mignon wellington with mushroom duxelles and brie fondue or our roasted half chicken with cornbread stuffing, mushrooms, and chicken jus.

Weekly specials include Happy Hour, as well as our 3-course Wednesday Wine Dinners, which curate pairings of wine with each off-menu course.

Reservations are recommended but walk-ins are always welcome.

Menu choices were varied and the meals that my family and I got very good (surf&turf and the tuna). The popovers were a little undercooked, but that is the only slightly negative review other than the fact that the noise level was a little high, but that’s to be expected with all the families that were there. Service was very good.

Two of us had the mussels for an appetizer and the were very good. The third member of our party had the calamari whidh he enjoyed. For our main course there were two filet mignons wellington which were delicious. There was an order of flounder which was also good. The chocolate cake and gelato desserts were also very enjoyable. Our waiter steve was very good.

As always both the food and service was outstanding. We shared the mussel appetizer to start and could not stop sipping the broth. The Tuna and Swordfish were both excellent.

Ambience of the place is great. You have choice of bar seating, indoor and outdoor seating. We chose to sit inside. our Server was wonderful. She was attentive and informative. We ordered the tuna nachos as a starter. We were greatly disappointed with it due to the fact that there was hardly any avocado or tuna on top of these fried nachos. I would say a half an avocado at most and four pieces of cubed. Tuna, each for the two of us definitely not worth ordering. In the past, the sushi has been delicious and fresh. This was not the case last night. I ordered the Spivey tuna roll and my fiancé ordered the H2O roll. Not only have they shrunk in size from the past. It just didn’t taste fresh. I had two drinks which were delicious and he had two drinks. The bill was $178! So for four drinks, one appetizer and two small rolls it was definitely not worth the money. They really have gone down in quality it was very disappointing. We will not be back

Another great meal here. Service was fantastic. Only thing that wasn’t good was the Cod milenanse. It was super dry and breading tasted burnt. Strange that this is on the seasonal specialties menu. Mussels appetizer was fantastic and so was everything else. Banana split a must for dessert
