It's “an authentic reproduction of New Orleans’ favorite watering hole,” which is cool to see, and although its Hurricane rum drinks could make you see double, there are truly two dueling pianists playing nightly. O’Brien’s serves good food, but if you can’t get a seat (or don’t want one), you can also grab a drink through a window facing the street. This spot is among the most popular here—the party starts at 4pm—and kids can join in. Cover is $7, usually after 9pm.
