Should you miss gay life à la New York, follow the flashing purple sign on the "main street" of Paris, near the corner of avenue George V. The place is often mobbed, primarily with gay men and (to a lesser degree) models, actresses, and the like. Look for go-go boys, drag shows, muscle shows, and everything from 1970s-style disco nights (Mon) to Tuesday-night foam parties in summer, when cascades of mousse descend onto the dance floor. Go very late.
