About this restaurant

  • Good for special occasions
  • Neighbourhood gem
  • Lively
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.

    Very nice restaurant, the food is good and the service is great. We went to celebrate my son’s birthday and he was surprised with a gift card, a very nice touch.

    Yet another outstanding dining experience at H2O. New appetizer is Onion Soup Dumpling and it's a home run. Salmon entree and swordfish entree were both excellent as well. H2O has a nice ambiance and vibe. The service and staff are great. Stephen was our server tonight. Attentive and personable adding to our dining experience.
