So-called “ruin pubs” are the hottest nightspots in Budapest these days. Located in abandoned courtyards and derelict old factories, these unusual hangouts capitalize on two international trends: vintage-mania and the romanticization of urban decay. How best to survey the trend? Start by ordering a Dreher (Hungarian beer) at the city’s original ruin pub, the 13-year-old Szimpla Kert, and try snagging a seat in the East German Trabant car, which has been repurposed as cozy restaurant seating.
