UALover: If you like Jewish deli food, drive down to the Rascal House. It's on the north side of Miami Beach. A very old favorite of mine.
Or, drive around South Beach, which is the very bottom part of Miami Beach. Take a walk down Lincoln Road Mall...very pleasant. If it's open (call first), have lunch at Joe's Stone Crabs, a real Miami landmark.
The Falls, south of South Miami on US 1, is a very pleasant mall at which to spend a few hours.
Or drive to Coconut Grove, park the car, and walk around there. Very nice shopping area with lots of restaurants.
