The Seattle’s Best Crab Cake Sandwich at Duke's Seafood layers a hefty crab cake made with Dungeness crab onto a bun with fresh toppings and a creamy sauce. The crab cake itself is the star, with a high ratio of crab to filler and a seared exterior that keeps the interior moist. Biting into the sandwich, you get a mix of soft, sweet crab, toasted bread, and crisp greens, with the sauce tying everything together. Menu notes about awards and house pride around this item reflect how central it is to the restaurant’s identity.
