I'm a BIG fan of this place. As I moved to Pittsburgh from New Zealand I needed to find a decent barber and was recommended this place by a friend.
MJ is my barber he actually gives a shit about what you want and what you're up to in your personal life unlike some other big chain salons.
Mister is probably the first place where I've actually felt comfortable in, where I can genuinely relax and be left in the trusted hands of my barber. The price is super cheap (my recent cut was $20 for a haircut and beard trim) which to me is a total steal!
If you want quality try Mister G&G
