About this restaurant

  • Good for special occasions
  • Neighbourhood gem
  • Great for creative cocktails
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.

    Always a consistently great experience when we dine at H2O. We were promptly seated and our server greeted us, friendly and professional. We started off enjoying fresh clams on the half shell, clean and tasty. Our mains were the everything crusted Montauk tuna, prepared black and blue. Melts in your mouth, perfectly prepared.IMHO, you’ll have a difficult time finding a better tuna entree. Our server and the manager checked in to be sure all was well and we appreciated their efforts to make this another wonderful experience. We appreciate all staff and thank you for another wonderful experience.
