I don't go as often since they left Trinity Bellwoods, but I'll still go back to Grateful Head for a cut from time to time and grab some schnitzel and perogies while I'm at it..
They've been consistently good and are priced in the zone for a good cut and style in Toronto. My kid gets his hair cut there, too, sometimes... a bit over the top for an 8 year old but I appreciate that they'll put the same effort into his hair as they will mine, and it's convenient to go to one place for both of us when weekends are busy. Good quality, honest advice on hair, no pretense. I generally really like the feel of this place.
