Few bars straddle the line between great after-work happy-hour spot and cool lounge, but the Science Club manages to be both. There are several floors at this hip downtown DC spot, but our favorite is the basement bar, where the concrete floors and low ceilings keep things cool and casual. Happy hour—Monday through Friday 5 to 8—includes $3 Yuengling, $4 Guinness, $4 Amstel Light, $5 house wines, and $4 rail drinks.
