Can anyone recommend any crab houses that are within walking distance of a Metro (preferably the red line, but orange/blue would also be OK)? I grew up eating blue crabs, so I'm looking for a place that's authentic (steamed whole with Old Bay seasoning) and reasonably priced. If anyone knows Bo Brooks in Baltimore (http://www.bobrooks.com/), then I'm hoping for that type of place here in DC. Any recommendations would be appreciated. Thanks!
