Luring crowds here and to a sister operation in Palm Beach, Charley's Crab gets 'em and keeps 'em with both the waterside setting with covered terrace, overlooking the Intracoastal Waterway. Shellfish and seafood in a variety of contemporary presentations, as well as old favorite treatments, are abetted by a satisfying array of steaks, chops, pastas, good salads, soups and desserts. A Sunday brunch is served here, too.
