Depending on your previous experience with haircuts, you’ll find the two-hour waits at Hi-Rollers Barber Shop either a deal-breaking inconvenience or a necessary evil. But nobody goes to Hooters for wings, and nobody goes to Hi-Rollers for a quick in-and-out. Between the amiable barbers and the steady rotation of Mob movies, this rockabilly-style shop is a complete haircut experience. 1120 S. Maryland Parkway., 702-382-6790. Tue-Fri, 9 a.m.-5 p.m.; Sat, 9:30 a.m.-4 p.m.
