Smithtown isn’t your typical suburb when it comes to seafood. I first figured this out after an impromptu dinner two summers ago. I sat at an unassuming little place off Main Street, expecting the usual reheated fare. Instead, what landed on my plate had the kind of freshness I still remember: plump shrimp, crisp vegetables, a tang I couldn’t put my finger on. That night, I realized my hunt for great seafood didn’t call for a trip to Montauk or the city—Smithtown itself was teeming with hidden gems.
If you like your seafood fresh, diverse, and skillfully prepared, this town delivers. From sushi bars with melt-in-your-mouth toro to casual shacks doling out buttery lobster rolls, Smithtown has a spot for every mood. Whether you’re all about the catch of the day or into inventive bites, you’ll find a lineup worth exploring. Stick around as I guide you through the best places, drawing on local favorites and a few tasty surprises tucked away from the crowds.
1. H2O: Seafood & Sushi
H2O: Seafood & Sushi impresses from the moment you walk in. The gray marble bar sets the mood for an evening that feels both relaxed and refined. My first visit ended with the memory of silky hamachi sashimi and Scottish salmon so fresh you could almost hear the ocean.
The seafood here isn’t flown in from just anywhere. The chef sources what’s local whenever possible, which means the menu reflects the best of Long Island’s daily catch. The sushi selection alone is a reason to return, with inventive rolls and classic nigiri done right.
If you try only one thing, order the Bluefin Tuna or Dive into the lobster roll. Each bite captures H2O’s love for quality and presentation. And for those moments when you can’t decide, the Wednesday Night Wine Dinners make choosing easy—and rewarding.
2. Nick’s Pizza and Clam Bar
Nick’s Pizza and Clam Bar feels like summer year-round, with picnic tables and seafood baskets taking center stage. The first time I visited, the scent of garlic butter and the sound of laughter pulled me in before I even glanced at the menu.
Nick’s blends a laid-back atmosphere with top-notch fare. It’s the kind of spot where families linger over platters of clams and friends debate the finer points of fried shrimp. The kitchen moves fast, but the food always feels thoughtfully prepared.
Start with steamers or the classic fried clam strips—they’re fresh, salty, and have just the right crunch. Pair them with a slice of their signature pizza for the best kind of surf-and-turf Smithtown has to offer.
3. Insignia Prime Steak & Sushi
Insignia Prime Steak & Sushi is where surf meets turf in grand style. Walking through the doors, I was struck by how inviting the space felt—equal parts chic and comfortable, with the kind of energy that makes any night feel special.
The seafood here commands attention. Their sushi is delicate and expertly shaped, as memorable as any you’ll find on the island. When I tried the tuna tartare and scallop sashimi, every flavor seemed perfectly tuned.
Order the sushi and the seared sea bass. The sea bass, with its crisp edges and tender middle, is a standout, and the sushi is an experience in itself. If you want variety with style, Insignia delivers without missing a beat.
4. Fresh Catch Market & Grill
Fresh Catch Market & Grill feels as local as it gets. Walking in for the first time, I saw cases gleaming with the day’s freshest fish—no need to wonder what is or isn’t fresh here.
The menu is built around what’s hauled in each morning, which means every dish lands on your plate at the peak of flavor. There’s a market vibe, but the grill’s got comfort nailed down, too.
Go for the grilled salmon or the classic broiled flounder. Each dish is pure, letting the seafood speak for itself. I especially love how you can grab something raw to cook at home or settle in for a simple, deeply satisfying meal right on the spot.
5. Triton’s Treasure Seafood Market & Grill
(631) 257-5266Call
Triton’s Treasure Seafood Market & Grill offers the best of both worlds—a working market with the heart of a true grill. From the first visit, I was drawn to the upbeat neighborhood feel and counters piled high with shimmering seafood, all sourced with care.
What makes Triton’s Treasure special is its genuine approach. Nothing is hidden here; you see the freshness before it ever reaches the grill. Their selection is always changing, depending on what’s in from the boats and market, and that means there’s always something new to try.
Try the grilled shrimp platter or the blackened mahi-mahi. They keep the prep simple and thoughtful, putting the spotlight on seafood that’s fresh, local, and full of flavor. This is a spot where quality counts, all in a friendly, bustling setting.
6. Wild Ginger
Wild Ginger is the type of place you look for when you crave something out of the ordinary. The interiors buzz with energy and the menu blends Japanese technique with local seafood in a way that feels fresh and unforced.
Every visit I’ve made has included a new culinary discovery, often starting with their sushi bar. The spicy tuna roll had a clean, peppery kick, while the yellowtail with jalapeño was vibrant and balanced—proof this kitchen understands its ingredients.
Order the sashimi deluxe or the pan-seared Chilean sea bass. Each plate is clean, bright, and thoughtfully prepared. For anyone looking for bold flavors with a gentle edge, Wild Ginger is tough to top in Smithtown.
7. the main catch
(631) 486-8864Call
the main catch takes Long Island’s bounty seriously. My evening here started with a plate piled high with local oysters—briny, cold, and unmistakably fresh. It’s clear from the first bite that quality and freshness drive this kitchen.
The vibe is classic yet unpretentious, making it a comfortable spot for both family dinners and date nights. The staff knows the menu inside out and always has a tip for what’s best that day.
Don’t miss the pan-seared scallops or their hand-rolled sushi. The scallops are sweet and tender, while the sushi is masterfully crafted and bursting with flavor. For true seafood lovers, the main catch lives up to its name, setting itself apart by letting top-grade local ingredients shine.
8. Claws Seafood Inc
(631) 862-4228Call
Claws Seafood Inc is the kind of spot locals hesitate to share, worried it’ll get too crowded. Tucked along Route 25A, the casual vibe invites you to relax and savor what’s on the plate. The first time I stopped by, friendly staff talked me into trying the catch of the day—something I didn’t regret.
The charm of Claws lies in its straightforward approach. No gimmicks, just fresh, carefully cooked seafood that lets the ingredients shine. The menu is tight but thoughtful, with a strong focus on local sourcing.
Go for the grilled shrimp platter or the baked cod. The shrimp have a clean snap and the cod comes out perfectly flaky. Here, it’s all about honest, flavorful seafood that tastes like a tribute to the waters around Smithtown.
9. Bonefish Grill
(631) 724-4012Call
Bonefish Grill in Lake Grove strikes a balance between polished and laid-back, making it a dependable spot for seafood cravings. I went in skeptical, expecting a chain vibe, but left genuinely impressed by both the flavors and attentive service.
The menu celebrates seafood with a playful twist, offering dishes that range from light and zesty to rich and filling. Everything is cooked to order, and the staff is always happy to help you navigate the choices.
The Bang Bang Shrimp is a local legend—crispy, creamy, and with just the right heat. If you want something straight from the grill, the wood-grilled salmon is always moist and flavorful. Bonefish proves that chain doesn’t have to mean uninspired, especially when the kitchen is firing on all cylinders.
10. Rockin’ Fish
Rockin’ Fish has a personality as big as its menu. Stepping inside, you’ll find music in the air and a lively crowd that keeps the energy up every night of the week. My first meal here came with great conversation at the bar and a dish that was crafted with more care than I expected from such a bustling spot.
This isn’t just a place to eat; it’s a spot to linger, chat, and try a little bit of everything. The kitchen knows seafood, cooking it with a confidence that’s tough to fake. Every detail feels deliberate, from seasoning to the crispness of their fries.
The fish tacos are always a hit, bursting with citrus and crunch, while the fried calamari is reliably tender. For something heartier, the grilled swordfish never disappoints. Rockin’ Fish blends a fun atmosphere with seriously good seafood—a combo worth seeking out.
