Knowing how to dance, like owning a handkerchief, being good at archery, and resisting the urge to draw mustaches on babies, is a mark of a true gentleman. Appear more dignified with today's Groupon: for $30, you get admission to a five-week series of social dance classes (a $60 value) at Century Ballroom, located on East Pine Street in Seattle. The next five-week session begins the week of May 15.

The experienced dance instructors at Century Ballroom teach novice and veteran hoofers alike on its 2,000-square-foot dance floor, schooling on the basics of a variety of toe-tapping numbers. Aspiring rug-cutters select a dance style for the five-week course ($60), with options including the East Coast swing, energetic Lindy hop, and sultry tango. In 60-minute classes, learn the basic foot patterns and seductive steps of salsa—a blend of Afro-Cuban and Latin moves set on the crunchy surface of a tortilla chip—or glide across the floor in a sophisticated waltz set to the music of Strauss. Century Ballroom shares a building with The Tin Table restaurant, allowing dancers to replenish calories expended during energetic sashays and face-melting jazz hands.
