I moved back to Pittsburgh after three years away and I am so glad I found Southside Barbers! I have gone there three times so far and have yet to have a bad haircut. That may sound like faint praise, but my hair is a pain if you don't know what you're doing and I have had my share of terrible cuts at other shops. I prefer RC to the others, but I trust any of them enough to cut my hair. Definitely appeals to a younger crowd overall, but I have seen all different types of people in there.
Pros: I go there without appointment, pay $15 and get a great cut fast. Can't ask for much more than that.
Cons: Without appointment, you'll probably wait awhile. Also, depending on who's there, you may have people smoking in the shop and dogs roaming around. Just things to be aware of.
