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.

    Your Chicken dish is what I primarily returned for. Always amazing! The server Steven was very attentive, engaging and efficient, as were the managers Jeremy and Tracy. Nice to see them even at the host desk. Thank you all for a lovely evening and for being so concerned about my food allergies.

    A wonderful Thanksgiving Day experience. The food was great and plentiful. Unique differences like the fresh baked pop-overs and candied ginger on the pumpkin pie made this a meal to remember. Our waiter Steven was exceptional This is the 4th time we’ve been to an H2O restaurant and every time has been enjoyable and memorable.
