Every Thursday afternoon before 5, a line forms outside the doors of this Heights hall of the Slavonic Benevolent Order of the State of Texas. And the line grows. And grows. For bingo. If you don't get there before 7 p.m., chances are the place will have reached its 700-person maximum, and the doors will close in your sad face. That's how popular this event is. It's not fancy — just a huge room with rows of long tables and folding chairs — and that's the way we like it. Plus, pitchers are only $7, and the burgers and dogs will help you keep your energy up for the fast-paced daubin'. (Bingo pads are $5 each, doors open at 5:15 p.m.)
