I've been going to Knock Out for about 2 months now. The first time I went was about 1pm on a week day and the place was busy. I immediately thought it must be a good shop if so many people go there during the week. The times I have gone I've had my hair cut by 3 different barbers and I must say that I'm not disappointed. I also love the whole boxing theme they have going on. Doesn't feel corny at all. I really like this place.
I recommend you check it out.
