Open since 1969, Bob and Barbara's is one of Philadelphia's most enduring dives, and the bar hasn't needed to change much to prove it. The Special, a PBR and a shot of Jim Beam for around five dollars, has been keeping the city honest for decades. Friday and Saturday nights bring live jazz, and the longtime drag show here is widely considered the longest-running in the country. Cash only, 21+, and exactly as worn-in as you'd hope.
