H2O Seafood & Sushi in Smithtown showcases seasonal seafood, served with passion, conceived with creativity. The sea dictates what’s on the menu at H20, as, whenever possible, our Chef sources local fish and supports local farmers through creative takes in the kitchen. Grab a seat at the gray marble bar while tasting fresh sushi or our modern American seafood classics. The sprawling menu features treats from the ocean; fresh Bluefin Tuna, Scottish Salmon and also satisfies land lovers with dishes like our flat iron steak or our pan roasted chicken. Shareable desserts like the donuts with coffee pot du crème make indulging almost impossible to avoid. Cleverly designed with an upscale New England feel, you’ll feel like home in this warm and inviting space. Weekly specials provide opportunities to taste the eclectic menu; like our Wednesday Night Wine Dinners showcase curated pairings of wine carefully selected to enhance each course
