My twin sister, who--despite my strong encouragement-- and due to computer phobia, won't post on chowhound, is going on an Art Deco tour of South Beach for four days next week, coming in from the snowy, cold Midwest. . Any suggestions I can pass on for breakfast, lunch, snacks, don't miss food? High end, headline restaurants aren't the only suggestions I'm looking for. But a great place to have a really good breakfast, a nonhigh-maintenance lunch or a place relax after a long tour, to chill and enjoy comfortable ambiance and GREAt food.
