In the area today with shaggy kid in-tow, I stopped into A & A and couldn't have had a better experience.
The shop only takes cash or check, two things I don't have. Khadim (owner) offered to but my kid's hair and let us hit the ATM afterward. He showed me some techniques so I don't butcher it next time I cut it and taught my little guy about straight razors.
Needless to say, the haircut looks great and we'll be back. If you live in the Willo District, or are looking for a good barber and can drive or lightrail it, A & A may be the shop for you.
