H2O Seafood & Sushi in Smithtown showcases seasonal seafood, served with passion, and conceived with creativity. The sea dictates what’s on the menu at H2O. Whenever possible, our chef sources local fish and supports local farmers through 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 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.
