The Hopvine Pub on 15th Ave. E. was once a somewhat more rough-hewn joint called the Five-O Tavern. The Five-O had hosted blisteringly-loud rock gigs in the mid-'80s. Even after noise complaints stopped those shows, it remained a hangout for young-adult heteros at a time when most other Capitol Hill bars were either gay or yuppie. It's now a finely-appointed microbrew joint, but still attracts some of the ex-Five-O crowd, with singer-songwriter gigs by the likes of Pete Krebs and Marc Olsen.
