Nestled in the sparkling waters of Casco Bay, Little Diamond Island is one of Portland’s most tranquil escapes—an idyllic retreat where the gentle sound of waves is matched only by the comforting sense of community. While this tiny, mostly residential island may not rival downtown Portland for sheer dining density, its food scene has a uniquely intimate charm. Here, island traditions, pop-up dinners, and waterside picnics are just as important as sit-down meals, and every meal comes with a side of stunning ocean views. If you’re ready to savor the best of Little Diamond Island, here’s where you’ll find the memorable bites and flavors locals love most.
The Island’s Social Hub: The Little Diamond Island Clubhouse
Located near the ferry landing at Harbor Avenue
Step off the Casco Bay Lines ferry, and you’ll soon spot the heart of Little Diamond Island life—the Clubhouse. This iconic gathering spot isn’t just an event hub, but also the community’s go-to café and casual eatery during the summer months. When open (usually weekends and select weekdays from late June through August), the Clubhouse offers:
- Fresh lobster rolls brimming with sweet, local meat for about $18—insider tip: ask for extra lemon
- Chowder nights that attract both families and visitors, featuring creamy clam chowder and hearty fish stew (typically $10-14)
- Breakfast sandwiches and fresh-baked pastries (around $4-6) on lazy weekend mornings, perfect alongside a hot mug of coffee
- Occasional themed dinner events, such as island BBQs or “taco night” with inventive fillings
Worth noting: seating is casual, and it’s as much about the community atmosphere as the cuisine. Grab a table outside for the quintessential island dining experience.
Seasonal Pop-Ups and Lobster Bakes
When summer is in full swing, Little Diamond Island transforms into a culinary playground with a distinctly Maine twist. Local residents and longtime summer renters often organize pop-up food events—a beloved tradition here.
- On holiday weekends and sunny Saturdays, keep an eye out for backyard lobster bakes hosted along Bay View Avenue or near the ferry dock. For around $25-35, you’ll enjoy steamed lobster, buttery corn-on-the-cob, and classic red potatoes, sometimes with blueberry pie for dessert.
- Some enterprising home chefs set up small food carts or stands (think iced lemonade, whoopie pies, or cookies, usually $1-3 each), especially near the ferry terminal on busy days. If you spot a hand-painted sign, don’t hesitate—these treats go fast!
Island Bakeries: Sweet Treats With a View
While Little Diamond Island doesn’t have year-round brick-and-mortar bakeries, local bakers make sure your sweet cravings are satisfied all summer long.
- On Sunday mornings, keep your eyes peeled for the “Sweet Island Bake Sale” table, often set up near the corner of Harbor Ave and West Point Ave. Talent local bakers offer everything from wild Maine blueberry muffins and lemon squares to rustic galettes and cinnamon rolls (prices range from $2 to $6).
- Residents rave about the homemade brown bread, a dense and molasses-rich island classic sold in mason jars. If you’re lucky, you might find it for sale after community breakfast potlucks or chowder nights.
Island Picnics and BYO
Because of the neighborhood’s laid-back, seasonal feel—and the absence of chain restaurants—one of the best ways to dine on Little Diamond Island is to pack your own picnic. Locals and visitors love to grab provisions from Portland’s mainland specialty shops before the ferry ride, then settle in at:
- The rocky ledges overlooking Hussey Sound for sunset sandwiches and local cheese
- The shaded town green for a family-style feast
Popular picks for BYO picnics include lobster salad from the Brown Trading Company, baguettes from Standard Baking Co., and gourmet provisions from Rosemont Market & Bakery. For a truly local flavor, try packing smoked mackerel or fresh oysters, both available from Portland fishmongers. Pair your meal with a cold Allagash White (grab a can from the Clubhouse when it’s open) and you’re set for island dining bliss.
Dining Destinations Just Across the Water
For those seeking a dinner out but willing to take a short ferry hop, the nearby islands of Long Island and Peaks Island beckon with additional options:
- On Peaks Island, check out The Cockeyed Gull (78 Island Ave.) for upmarket bistro fare and water views, or The Inn on Peaks for seasonal, locally sourced dishes—both are just a short ferry trip from Little Diamond Island.
- Long Island’s Boathouse Beverage & Tapas (576 Island Ave.) offers small plates and craft cocktails in a lively, casual setting, making it a favorite for a Saturday adventure.
Beloved Local Traditions and Hidden Gems
*The Community Potluck*—Ask any resident about the must-try dining experience, and they’ll mention the summer potlucks at the Clubhouse or neighboring cottages. Each family brings a signature dish, turning the evening into a parade of homemade chow, from fried clams and pulled pork to secret-recipe berry crisps. If you’re visiting, ask around and don’t be shy—visitors are often welcomed with open arms and a heaping plate.
*The “Honesty Cooler”*—Keep an eye out for the legendary “honesty coolers” at the ends of certain docks and driveways, where local kids and creative cooks leave cookies, sodas, and sandwiches for passersby. Simply drop your cash in the jar—it’s a throwback to old-school island trust and neighborliness.
Summer Food Truck Visits
Occasionally, a licensed Portland-based food truck will visit Little Diamond Island during peak weekends (watch for announcements posted at the Clubhouse or passed along via text chains). Favorites have included:
- Bite Into Maine, famed for their lobster rolls and creative takes on Maine classics
- The Lobster Shack truck, bringing fried seafood baskets to delighted islanders for $10-16 per meal
Because these visits are rare and weather-dependent, check with locals or the Clubhouse for the latest schedule.
