I have never received a bad haircut from this place. I have been coming here for a few years and they are very versatile in the styles of cuts they can pull off. I've seen them cut smaller children and older men. They even do style cuts on females from time to time.
The only problem I've ever had with South Side Barber is that they are very unpredictable as far as what staff is going to be working. It's incredible that they are open seven days a week and even offer appointments (for an up charge) but if you like a specific barber, it's hard to tell when he's there.
Wait times are like any barber shop. Hit or miss. Go on a Friday or Saturday, you're gonna wait a bit. Sunday through Thursday though, you're out in less than an hour.
