It's only a year old but already the Dolphin Mall has its devoted fanatics. One of the appeals is variety: more than 200 stores running the gamut from low-end to high, from Burlington Coat Factory to Bebe. There are also outlets (Off 5th, Bombay), offbeat gift stores (Exotic Treasures), and standard mall fare (Old Navy). The outdoor area invites you to lounge in the sun with a smoothie in hand. The indoor-minded can play Skee-Ball at Dave & Buster's, sip a café mocha at Borders, or watch would-be rock gods strum guitars at Mars. Clearly this mall wants you to sit down and stay awhile -- then get back up and shop till you drop.
