Located across the street from the adult probation department, the Roadrunner is a true dive-bar. The drinks are cheap enough, and the beer cold enough, but there are better dive bars in the general vicinity such as the Tally-Ho, or the Playa.
But, if you live close by and not in the mood to drive, or have a few minutes before you have to meet your probation officer, stop on in and have a cheap drink. That's what I did.
