No, this Dive Bar isn't actually a dive — far from it, in fact — but the name makes perfect sense once you find out a little more about it. See, the centerpiece of this K-Street haven is a massive 7,500-gallon aquarium that regularly features appearances by a live mermaid or merman, making it one of the area's more interesting places to grab a drink. The drink options include cocktails, draft beers, and wine, all of which taste even better while enjoying some of the live entertainment that's often being played in the roomy space.
