Across the street from the Diamond Club, a seemingly endless line of nightcrawlers wraps around the corner, waiting to get into Level. Cars cruise along Washington Avenue, drivers honk their horns, and passengers try to pick up women traipsing around in tight-fitting clothes that show off lots of cleavage. It's a typical night in South Beach. But inside this pool joint, patrons are focused on only one thing: sinking a shot, preferably the eight ball. Diamond's cool atmosphere, spacious layout, and plentiful tables make for a primo pool-playing place. And the wide, wonderful view of Washington Avenue will tantalize those who must people-watch as they rack 'em up. Plus it is open way late -- till 5:00 a.m. seven days a week.
