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.

    While a bit of a higher priced dinning experience (expect to spend $80+ per person), never a bad experience, food is always stellar and the service is excellent. Highly recommend.

    We took our grandson to H2O to celebrate his 21st birthday. Our dining experience was wonderful. Be prepared to spend. Our cocktails were $18 per glass.
