Visitors with a penchant for pastels and portholes should make this South Beach structure their first stop.. In Short The friendly volunteer staff here considers themselves to be the ambassadors of the Art Deco District. Run by the Miami Design Preservation League, whose on going efforts have saved South Beach from the developer's bulldozer, the center offers an assortment of tours. Aside from weekly walks of historic South Beach, it also sponsors monthly tours of Lincoln Road, private gardens, the Miami Beach waterways and even an "Art Deco Underworld" tour of Al Capone's prohibition haunts. The center sells all kinds of collectible souvenirs, but this is cool kitsch, definitely a step above your typical tourist trap gift shop. It specializes in reproductions of antique postcards, vintage deco travel posters and home accessories with the streamlined look. Best of all, proceeds benefit the league's preservation efforts.
