I had to throw a bachelor party for a bunch of guys in their twenties. We started out doing the go cart thing at Unser Karting and it was a blast. Dave & Busters or something similar is always good clean fun for grown men as well.
This was going to be my suggestion if Denver is an option.
Unser is a blast. It's sorta pricey, but worth it IMO.
Living the fall of an empire sucks!
