The song of summer 2014 is still up for debate (though Rihanna is putting up quite a fight), so while that gets sorted out, revisit the hits of the past at this epic greatest hits throwdown. Attendees are welcome, nay, encouraged, to belt along to projected music videos such as Will Smith’s “Miami” and Ace of Base’s “The Sign” without fear of ridicule. Prep for the ’90s costume contest with a grunge-band tee or by coiffing your hair into a J. Timb–style frosted mop, and practice your Roger Rabbit and Running Man for the dance-off (prizes include free drinks and concert tickets). Special cocktails ($7) include the Walkin’ on the Sun, a rum-and–St. Germain lemonade that’s sure to get you smash(mouth)ed.
