John Kelly has a good one, Hopefully he chimes in.
Art of Shaving either at Mandalay or Fashion Show Mall is good...if you want cheaper go to the South Point's barber shop which is about a 20 minute drive from where you're at south part of strip.
I visited The Art of Shaving last week.
Given my current losing skid, I'll stick with my Gillette Mach 3 razors.
I once paid $120 for a haircut at Vidal Sassoon in Beverly Hills.
My girlfriend at the time cracked, "That's $20 per strand of hair."
Funny but not nice.
