Time Out says
Captain White is located within the Maine Avenue Fish Market, a bustling DC institution teeming with seafood just-plucked from the ocean and bay. The market is the longest continually running market in the United States and Captain White is a major player. This stalwart hums with energy as fishmongers fling the day’s catch onto a bed of ice or corral anxious lobsters that can sense their fate. Captain White’s lets you pick your fish and cooks it to your liking on the spot. A tip: You’ll find some of the best prices for fresh crab in town here, so think twice before settling for that imitation stuff.
