Once I discovered Coiffure Pierre, I never went to another barber shop while I lived in Montreal. They had a great student rate ($13, and they didn't even ask if I was a student--or maybe it was obvious). I always got a great cut, which lasted as long as two months. Hey, I put off haircuts a lot.
The attention to detail was likely a factor: they would always go around the ears and neck with a straight razor and hot shaving cream. And when getting a cut in December, they'd even give you a shot of schnapps.
Coiffure Pierre used to be further south a few years ago (near Bleury and St. Catherine), but they moved to this location on Sherbrooke, which is in a nicer building. It was also nearer to me and other people living in the McGill ghetto.
