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, led by Executive Chef Dayven Alonso, 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. Shareable desserts like the donuts with coffee pot du crème make indulging almost impossible to avoid. Weekly specials include Happy Hour, as well as our three-course Wednesday Night Wine Dinners, which curate pairings of wine with each off-menu course. H2O was recently voted #1 Overall Seafood Restaurant in the New York Area on OpenTable. H2O is a Surfrider Foundation-certified “ocean friendly restaurant,” a designation given to restaurants committed to making sustainable choices, such as eliminating single-use plastic.
