I'm not really sure what I can add to this place that hasn't already been said. The shave is the manliest foofoo thing you can possibly do; a fantastic experience that IMO was worth every penny. The haircut was rock solid. We walked out of there feeling like a million bucks.
As others have mentioned, they do pitch but not push their products. My barber did recommend a couple of things, but didn't dwell on it or make me feel guilty for not wanting to purchase it.
A trip here has now become standard for a trip to Vegas.
