Finally a place in misquamicut where you can get boiled lobster and steamers! The steamer portion was huge. Clam chowder was great too. Seafood Haven has the only clam fritters I’ve ever actually liked. And its great to actually have fried shrimp that is more shrimp than batter. A great selection of quality seafood and a friendly staff make Seafood Haven a gem at the beach.

If you’re anywhere near Wakaneau Beach, do yourself a favor and stop at Caswell’s Seafood Haven—this place lives up to its name! I had the fish sandwich, and it was absolutely delicious—crispy, perfectly cooked, and served on a soft, toasted bun. It came with thick-cut fries, a bright lemon wedge, and the best coleslaw I’ve had in a while. The slaw had Brussels sprouts and kale mixed in, which gave it a super fresh crunch and nice flavor balance. We also tried the clam chowder—rich, creamy, and exactly what you want from New England-style chowder. The side of hush puppies was a bonus treat—crispy on the outside, fluffy inside, and perfect with the dipping sauce and lemon. Everything was served fresh, and we enjoyed our meal outdoors with a relaxing seaside breeze. Whether you’re just off the beach or looking for classic seafood in a casual spot, Caswell’s is a must-visit.
