If you're gonna go classic straight-razor, then follow the elite. Beverly Hills's oldest barbershop has been serving the likes of Clark Gable, Frank Sinatra, and Ronald Reagan since it first opened its doors in 1936. It's even rumored that Bugsy Siegel had a few uncomfortable conversations with Mickey Cohen here while getting clipped (before getting clipped).
