I've tried quite a few shops in Scottsdale. None really stood out. I would just stop in one whenever I was around and had some time. Had been to Barbershop Jack several times as well. Always had a good cut there. However, yesterday I received THE BEST haircut I've had in my life. Both Don and Dennis are great! If you like a real barbershop experience, check them out!
As to the post regarding walk-ins....I'm always a walk-in. Sometimes, they're busy and I make an appointment for later. Other times, they've taken me right in. It's a great place to wait - beverages, sports on TV, etc. But, if you're pressed for time, make an appointment.
