If you're not averse to waiting in line for up to an hour, you might get a table here in season. The line begins forming early -- there's often a wait at lunch as well. It's as much to do with the size of the joint as its food. It's a small fish shack set in a strip mall. The L-shaped tiki-hut bar takes up a good amount of room, so the wooden tables and bench seating in a sparse space are crushed together, and the volume is sometimes shoutable. (Claustrophobes beware!) But there's another reason for the wait: The fresh sushi and sashimi (signature is a lobster volcano roll), fresh fish dishes, and chowders draw fans in droves. Complimentary edamame comes to the table; then diners must choose from among a list of fresh fish of the day or standard whole snapper (fried and standing up on the plate in an unusual presentation), lobster mashed potatoes, or crab-crusted hogfish. For those who can't wait: Takeout is an option.
