SOFT SHELL CRAB BURGER IN CASTRO VALLEY, CA BASA SEAFOOD EXPRESS CASTRO VALLEY, CA I love how simple and straight forward these seafood burgers are! Soft shell crab is my all time favorite. Top it off with hot chili oil and it’s game over! Have you been here before? #basaseafoodexpress #softshellcrab #friedoysters #seafood #castrovalleyca
