During the week, lawyers and judges come to unwind at the Cadillac Bar, set in a historic stucco building near the Bexar County Courthouse and City Hall. On the weekends, singles take over the joint. A DJ spins on Saturday nights, but on Thursdays and Fridays, the sounds are live and local -- anything from '70s disco to classic rock to pop. Full dinners are served on a patio out back.
