I have been to the Penthouse...

I have been to the Penthouse Club in Denver 3 or 4 times. I always have had fun (although I always do at Strip Clubs). The traffic can vary highly, jam packed one night, almost no one in there other nights. The club is physically huge, with a kind of elevated entrance with full bar, and a massive (like the size of a football field) sunken area with multiple poles and lots of seating.

The VIP area is upstairs and is pretty standard fare. Multiple little booths with curtains that can close. Pricing is pretty typical of a strip club. Expensive drinks, etc. I seem to remember that lap dances were fairly expensive, like over $20.

My best experience is when I went with my wife. All of the dancers treated her like a queen and the amount of attention she got was ridiculous (I have to admit I got jealous a bit LOL)
