If you've been to the MVP Modern Barbers in Kensington, this one seems a little smaller, but the service is the same: walkin haircuts for about $30, TVs everywhere, hot towels, scalp massage, and a complimentary drink. Plus, they have a dog, a big bulldog named Mack.
I used to work in the same building as the Kensington MVP so I could pick a good time to walk-in, but if you can plan a day in advance their online appointment site is handy.
