Portsmouth, NH doesn’t just serve seafood; it sets the table for something memorable. This coastal city is a magnet for seafood lovers. Whether your cravings lean toward fire-grilled fish or a basket of crisp fried clams, Portsmouth delivers every time. On my last visit, I decided to put the city’s reputation to the test by wandering its historic streets and sampling both iconic landmarks and hidden treasures. Let’s just say, even a picky eater will find a favorite before sunset.
There’s a different kind of energy in a city that’s hugged by both river and sea. I found chefs here quietly obsessed with freshness and tradition. Some spots brought me to the edge of the pier, salt on my skin and a simple lobster roll in my hands. Others made me swap my t-shirt for something proper, but kept the flavors just as pure. If your idea of happiness starts and ends with a good meal from the ocean, Portsmouth’s lineup is worth your appetite. The seafood scene here is deep, diverse, and—if you know where to look—always satisfying.
1. Jumpin’ Jay’s Fish Cafe
Jumpin’ Jay’s Fish Cafe, just steps from downtown Portsmouth, feels like the city’s unofficial embassy for seafood lovers. The bright, modern dining room draws a buzz, yet each plate arrives with serious focus. On my first visit, the grilled swordfish—seasoned just enough to showcase its clean flavors—made me rethink simple cooking in the best way.
The chalkboard specials are always worth a look. Oysters arrive cold and briny; the fried calamari stays tender, not rubbery. The crab legs win fans with their generous size and sweetness. For a taste of Portsmouth’s seafood scene at its finest, start with the steamed clams or the grill specials. The attentive staff and local vibe make it easy to linger, and the desserts dare you to save room.
2. Blue Mermaid
Blue Mermaid brings a sunny twist to Portsmouth’s typical seafood scene. The vibe is laid-back, almost like wandering into a friend’s backyard for a cookout—if that friend knew their way around Caribbean and Latin American flavors. My first bite of their fish tacos had just enough tang and heat to keep things interesting.
The Mermaid’s Caribbean seafood chowder sets the tone: rich, herby, and just uncommon enough to stand out. Ask for the jerk shrimp, which capture the playful heat and deep flavors this spot is known for. The grilled mahi-mahi is another solid choice, always fork-tender and brightened by the house salsa. This isn’t your standard seafood joint—it’s where Portsmouth’s harbor meets the tropics on a plate.
3. Top Claw Lobster and Seafood Limited
(603) 766-0451Call
Top Claw Lobster and Seafood Limited is a no-nonsense stop for anyone craving impeccably fresh seafood. At my last visit, I stood at the counter torn between lobster rolls and fried haddock. The decision became easy once I spotted a fresh batch of lobster rolls leaving the kitchen—they don’t skimp.
The lobster roll is the star here: generous chunks of lobster, lightly dressed, and set in a soft bun. For something warm, the clam chowder comes loaded with chunks and a briny depth that points straight to Portsmouth’s docks. Simple prep and quality ingredients rule the day. If you want old-school, harbor-to-table seafood without fuss, Top Claw delivers every time.
4. Row 34
Row 34 is the spot locals reserve for an upscale seafood fix. The space is sleek but relaxed, buzzing with the kind of energy you get when the oysters are top quality and the taps never run dry. My first order here was a plate of their signature raw oysters—impeccably fresh, reflecting the best of the local harvest.
Oysters are what Row 34 is known for, served in a rotation that keeps things interesting. Try the crispy fish sandwich or the expertly seared scallops, both standouts for their balance of pure flavor and technique. Their lobster roll also gets high marks for its generous serving and perfectly light dressing. If you want seafood done right, Row 34 won’t let you down.
5. Orion Seafood International Inc
Orion Seafood International Inc isn’t your classic sit-down spot; it’s more of a hidden powerhouse in Portsmouth’s seafood supply chain. My first introduction was through a chef friend, who swore by their dedication to freshness and consistency. When top local restaurants need the best, Orion is the trusted source.
Here, quality is everything. While they mainly serve wholesale, some lucky visitors get to sample standout catches if they stop by at the right time. Ask about what’s in season—halibut, scallops, or even just-caught flounder. The selection reflects the work of a team that lives seafood, day in, day out. For anyone serious about their seafood, Orion is where many Portsmouth menus begin.
6. Geno’s Chowder & Sandwich Shop
Geno’s Chowder & Sandwich Shop is proof that the best seafood in Portsmouth doesn’t need flash. My favorite seat is on their waterside deck, watching lobster boats drift by as bowls of hot chowder steam on the table. Geno’s has stuck to family recipes since 1964, and you can taste every bit of that tradition.
Start with their signature chowder, rich with clams and full of flavor. The lobster roll is generous, lightly seasoned, and a reminder that less is sometimes more. If you want “old Portsmouth” on a plate, go for the simple fried fish sandwich. Warm staff, honest food, and a real sense of place keep people coming back, season after season.
7. Boathouse Restaurant
Boathouse Restaurant isn’t just about food—it’s about the view. I still remember my first meal on their deck, soaking in sunset over Sagamore Creek with the taste of fresh scallops on my plate. This family-owned spot has earned its “where the locals go” claim with consistency and charm.
The seared sea scallops should be your first choice: locally sourced, rich, and cooked just right. On breezy days, a bowl of their creamy clam chowder feels like comfort food done the coastal way. Order the fisherman’s platter if you want variety and value. The atmosphere here is relaxed, the staff friendly, and the seafood always lives up to the scenery.
8. The Oar House
The Oar House offers an old Portsmouth charm that feels both historic and welcoming. My first night here was marked by live piano music, a bustling bar, and the kind of seafood that makes you want to linger. You don’t just eat here; you become part of the steady rhythm of the waterfront.
The baked haddock is a true standout, flaky and tender with a buttery crumb topping. If grilled fish is your thing, their salmon comes right off the grill, smoky and moist. Their chowder pairs perfectly with the view of working boats right outside the window. Consistent quality, attentive staff, and atmosphere set The Oar House apart from the crowd.
9. The District
The District has a modern vibe that fits right into Portsmouth’s eclectic downtown. My evening started with people-watching from a window table and ended with a meal worth talking about. This spot champions both creativity and local sourcing, raising the bar for seafood in a city that’s already known for it.
The pan-seared local catch is always a smart choice, expertly cooked and served alongside bright, seasonal sides. Their seafood stew offers bold flavor and highlights the kitchen’s playful side. Don’t skip their weekend brunch if you’re craving something different; their seafood options deliver freshness in every bite. For a contemporary take on classic New England fare, The District never disappoints.
10. The Franklin Oyster House
The Franklin Oyster House takes a deep dive into Portsmouth’s oyster tradition, but adds a modern spin. My first time at the marble oyster bar brought that rare thrill of tasting local varieties side by side, each with its own subtle flavor. The energy here is contagious, with the kitchen sending out small plates as fast as the shuckers work.
The raw oyster selection is second to none, always featuring a fresh array from local waters. If you like to share, order a round of their seafood small plates; each one highlights the kitchen’s creative style. The house-cured seafood options are an unexpected treat, marrying classic tastes with a twist. Franklin’s is where old Portsmouth and new ambition meet on the half shell.
