Miami is a late-night kind of place, so it makes more sense for happy hours to begin late. At Fox's little den of iniquity, it's two-for-one on whatever you're drinking (barring the top shelf and imported beer), from 11:00 p.m. to 2:00 a.m. on Tuesday and Saturday nights. "It's standing-room-only, honey -- a lot of fun," assures the bartender in her smoke-deepened cackle. Fox's is a timeless, crimson-hued twilight zone, the darkened Fifties lounge of beat poets and deadbeats, of those looking for their future ex-wives, of slumming college students and aging hipsters. Slip down low into the deep booths. Enjoy the sounds of the free house jukebox, which admirably covers every era since the place was founded in 1946. Have a drink. Have two. (Fox's also hosts a conventional happy hour from 4:00 to 6:30 p.m. every day.) Hours: 11:00 a.m. to 2:00 a.m., Monday through Saturday; 5:00 p.m. to midnight Sunday. Hungry? Fox's prime-rib special is way cool.
