Ri Ra has a few locations in the DC area - one of them being located on a back street in Bethesda. They offer some decent happy hour drafts and their dinners are good as well. They seem to specialize in things with Irish influences, such as corned beef and Guinness drafts. The Guinness here is some of the best to be found in the city. The atmosphere reflects a pub-like feel. If you are in the area, definitely worth checking out.
