About

It's no secret that Bar Harbor is home to fresh seafood. One local dining spot that showcases oysters and creative cocktails is The Barnacle. Located on Main Street, this locally operated seafood spot has deep ties to Maine's aquaculture, which supplies it with the ocean's bounty.

The eatery opened in 2021, offering a simple menu focusing on quality over quantity. Housed in a historic brick building that oozes maritime charm, The Barnacle operates under an environmentally friendly model that supports local fishermen and harvesters.

Every oyster is shucked with care, showing just how much the team values quality and responsible sourcing. The menu also offers non-seafood options such as paninis, sandwiches, and chili. Additionally, the menu rotates with the seasons and with what's available from the farms and oceans surrounding Bar Harbor.

It's for these reasons that The Barnacle has become a go-to spot for serious seafood fans. With its "ocean to table" approach, visitors get a taste of Maine that's both pure and memorable.

Vibe

While the building is narrow, you can't miss its deep blue facade and classic wooden sign. The historic storefront stands out on Main Street, its windows and doors like portals of a ship, letting passersby catch a glimpse of the restaurant's interior.

The interior of the shotgun-style restaurant blends rustic coastal charm with a polished, modern feel. Exposed brick walls, weathered wood floors, and shiny bar tops set a relaxed but stylish tone. Vintage maritime maps and brass ship lanterns on the walls add history and character.

The atmosphere is casual enough for anyone to relax after hiking Cadillac Mountain, yet polished enough for special occasions.

The wraparound bar is the main attraction, drawing guests who want a front-row seat to the action. Here, bartenders mix craft cocktails while shuckers open oysters at lightning speed.

Aside from the bar, high-top tables in the room are perfect for sharing plates and conversation. When summer rolls around, sidewalk tables allow diners to watch downtown Bar Harbor come to life.

The relaxed coastal vibe at The Barnacle will be a memorable part of your Bar Harbor vacation.

The Barnacle: Menu & Drinks

The main attraction is the fresh oysters. These delights of the sea are served on ice with a zesty, house-made mignonette that complements the briny flavor. People often mention the oysters' freshness and note the care put into shucking—always clean, always smooth.

For those looking beyond oysters, the smoked trout deviled eggs are a favorite starter. These deviled eggs have a rich, smoky flavor from the local trout, a hint of paprika, and a silky yolk filling that makes this appetizer memorable.

The Maine crab roll is another go-to for regulars, offering a lighter, sweeter alternative to more traditional seafood sandwiches. The crab is dressed and piled high on a warm, toasted split-top bun, allowing the flavors to shine through.

The sandwiches are a welcome relief for land lovers, with the paninis being a standout. The Pastrami Reuben Panini features black pastrami, sauerkraut, Swiss cheese, and Thousand Island dressing. This warm and filling handheld comes with chips and a pickle.

A hearty and warm dish is the House-made Flatliner chili with seasoned beef, beans, green peppers, onions, and the right amount of spices. It's perfect on those cool, Maine days.

When it comes to drinks, The Barnacle shines! Cocktail fans will want to try the Blueberry Bucha-tini, featuring Maine-made blueberry kombucha and premium vodka. A splash of raspberry seltzer adds a lovely twist to this creative beverage.

Beer lovers will delight in the 23 taps that rotate with the seasons. While the wine selection is limited, what is available pairs well with the menu. Additionally, there are plenty of non-alcoholic drinks, ensuring something for everyone.

Dining at The Barnacle lets you enjoy bold flavors and tried-and-true regional favorites, all served with care and attention to detail.
