H2O Seafood & Grill in Smithtown offers a polished, coastal-inspired dining experience built around fresh seafood, modern American flavors, and an atmosphere that feels both upscale and relaxed. Whether you're celebrating something special or simply in the mood for quality food in a refined setting, H2O delivers on every front.

The interior blends clean, contemporary design with nautical touches — think soft lighting, ocean tones, and subtle wood and stone accents that create a warm, modern ambiance. The space is inviting without being too formal, making it just as suited for date night as it is for a business lunch or weekend dinner with friends.

At the center of the experience is the food — fresh, thoughtful, and beautifully presented. Raw bar selections like oysters, littlenecks, and shrimp cocktail are a great way to start, offering a taste of the ocean with clean, briny freshness. Entrées range from delicately prepared halibut and pan-seared scallops to lobster tails and sushi-grade tuna. For those looking beyond seafood, options like the dry-aged ribeye or short rib pappardelle are just as satisfying.

Portions are balanced, flavors are clean, and the ingredients shine without being overcomplicated. Attention to detail carries through from the starters to the desserts, which include standouts like key lime tart and warm chocolate cake.

The drink menu holds its own, with a sophisticated cocktail list and a wine program that covers both international and Long Island vineyards. Seasonal cocktails and house infusions offer creative choices, and the bartenders are knowledgeable and attentive, able to craft a drink that complements your meal perfectly.

The best time to go? Evenings are ideal, especially on weekends when the dining room is lively but never overwhelming. The vibe is calm, confident, and coastal — everything you want in a modern seafood experience.

H2O Seafood & Grill brings elevated dining to Smithtown with the kind of consistency, flavor, and style that keeps guests coming back for more.
