Unless you live in Mayberry, there's a pretty good chance your local barber has been replaced with a froufrou salon. As a result, the good old-fashioned straightedge men's shave has been nearly wiped out. That's why the opening of the Art of Shaving's first West Coast barber spa, in Mandalay Bay's ritzy Mandalay Place shopping promenade in Las Vegas, is such a breath of fresh Barbicide. Guys, treat yourself to a Royal Shave: a 45-minute, $45 indulgence involving hot towels, essential oils, and a whole lot of pampering ― you'll toss your Mach3 straight out the bathroom window. Appointment required. www.theartofshaving.com or 702/632-9356.
