It's what Long John Silver's pretends to be but never has been: good seafood on the fly. Capt. Crab's has the fish sandwiches (fried and grilled), the shrimp, conch, clam chowder, and so on. But especially notable in this little shack of a fast-food restaurant are the crabs. A moist and delectable crab sandwich goes for $6; a bucket of heavenly garlic crabs ranges from the one-pounder at $8.50 to the jumbo tub (four pounds) for $29. Pair it with a cold beer, sold by the bottle at the drive-though window, and a two-dollar key lime pie and you're good to go. The drive-thru is open 11:00 a.m. to 11:00 p.m. Monday through Saturday.
