At Club Tropicana, the tables may seem empty, but that doesn't mean you can sit down at them. Die-hard dancers get there early and claim their seats with napkin- covered cocktails. Of course, you probably won't even think about sitting once you get to shaking your ass on the dance floor. On typical weekends, Latin bands with lots of members play a nice mix of bachatas, merengues and salsas. Feel free to stare in amazement at the effortless twirls and fleet feet of the regular patrons.
