What, exactly, is the Rose? The impressively generic name, covered windows and website that promises only "Portland's newest nightlife destination" give away very little about the business that took over the former Beauty Bar space. As best I can describe it, The Rose (111 SW Ash St., 544-7330) is “Portland does a nightclub.” The repurposed wood bar, exposed bulbs and brick walls say "Hey, we're south of West Burnside," but the thumping dance music, plastic cups and audio-synced lasers say "Woo, Old Town!" On Wednesdays, Baby Ketten Karaoke collides worlds, as guys with neck beards belt rock songs below swirling disco lights while a promoter suggests this year's Halloween night theme be "villains and super-hos" because, a female patron agrees, women love dressing slutty for Halloween.
