Tonight in Ballston: Cafe Scientifique on Climate Change

I've never been to one of these, but I've heard good things:

Aug 4, 2009 Cafe Scientifique: Weather and Climate

Short presentation starts at 6:30 p.m. The current location is at the atrium in the National Science Foundation (NSF) building in cooperation with The Front Page Restaurant, 4201 Wilson Boulevard, Arlington between Wilson Boulevard and Fairfax Drive, and one block south of the Ballston-Marymount University Metro stop on the Orange Line.

Some added incentive to check it out -- according to Arlington's Twitter feed, there are also half-priced burgers starting at 5:30pm.
