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.

    This is the second time coming here and I wish it was closer to me because I would make it a point to come more often. The food was absolutely delicious. We shared the wedge salad (could have used a little more dressing) was very good and we shared the calamari. This was crispy and very tasty! For the entrees I had the special, pappardelle with short rib and butternut squash. It was absolutely amazing. The server asked if I wanted the appetizer portion or the full entree and because I knew my daughter would want some i ordered the full size which to my surprise was so small and was prob the app size. But delicious all the same. We shared the affogato for dessert and enjoyed that very much. I do have to say it was EXTREMELY loud and I felt like we were shouting. The parking was difficult, it took 15 mins to find a spot. So get there early. I would definitely go back!!
