Meet Black Betty, The Fifth’s younger, wilder sister (perhaps, now, the easy one)—who likes to smoke. A lot. When The Fifth underwent renovations last year, an adjacent (but functionally separate) space was designed as a refuge for frostbitten smokers and a mecca for lovers of rock ’n’ roll. Swathed in dim red light and a slight haze, the room reaches capacity most Thursdays. The jeans and T-shirt crowd (no dress code, unlike its sibling) punch approving fists in the air and sing (or shout) to the likes of Nirvana, Metric and Guns N’ Roses, while trendily waifish male bartenders grab megaphones to call all willing ladies to dance atop the bar—or have a twirl around its brass pole. One night, the barmen were so stirred by the rock vibe that they started throwing napkins into the crowd like confetti. There’s no beer on tap, but most opt for edgier shots of Jack Daniels ($7) anyway.

Tip: If you forget your smokes, there’s a now antique Benson & Hedges display case at the bar ($6.50 a pack), illuminated by six-foot backlit posters of '70s rock icons Alice Cooper and Elton John.

Black Betty, 225 Richmond St. W., 416-979-3000.
