I moved back to Vegas after a few years in LA. Vegas does a lot of things right, but barbers aren't one of them. Too many people are happy with careless trash like sportclips and supercuts or a barbershop with a purposefully misspelled name that doesn't take reservations. In the end you end up lopsided or looking like forrest gump.
After a month of looking at reviews, I found Truman's. Awesome attention to detail, he takes appointments online, and his shop is comfortable.
Have some respect for your hair and your time, and make a reservation.
