About this restaurant

Good for special occasions
Neighborhood gem
Great for outdoor dining

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.

We visited for restaurant week. The selection was good. For appetizers we had the warm goat cheese salad (nice size) and lobster and shrimp wontons. Both were enjoyable. For our entrees we had the flounder and tuna both were exceptional. Dessert was Caramel gelato and and a lemon tart. These to were good. My wife enjoyed her drink special (Hampton spritz). Overall it was not crowded (Sunday evening) and an enjoyable evening.

As always, the food was very good. The popovers are one of their specialties and did not disappoint. Startsfr restaurant weeks were all excellent. The tuna with everything spice was tasty but a tad heavy handed with the salt per one of our group of 7. Service as always was friendly and helpful. A nice place to have celebrated my birthday,

Some hits and some misses here. Popovers are 10/10. Baked clams were just ok. Lobster and shrimp wontons could have probably been good but weren’t hot. It was recommended that we order the crusted tuna raw so we did and it came out medium. Wasabi mashed potatoes were realllyyy good, same with French dip.

We usually gave a good experience but not this time. Maybe because of Restaurant Week, but the food was terrible and my meal was cool not hot. I requested cod fish and didn't realize it was breaded because it wasn't in the description of the selection. I hope it was just this time, but I'll avoid coming back during restaurant week in the future.
