I was just in Denver and I had the pleasure of visiting 1up. Such a phenomenal selection of pins, MM, SS, FGY. An excellent mix of old and new, just a wonderful place to play. They had at least 10 games. The games were maintained very very well. All the flippers were strong, all the lights were bright and in general the play fields, cabs, and the overall condition of the games were tops. All the games were priced very reasonably as well. I didn't eat, but the cheeseburger and fries looked great!
If you're ever near Denver bring quarters because I think you'll be there a while. I know it's been said before, but I just wanted to offer my 2 cents on the place.
