The Manitou Penny Arcade is one of the best arcades I have been to. It has a ton of old and new. They have about 250 machines, some of my favorites are the old baseball games. My wife takes my son and me there every year for my birthday. Pretty cool place. The address is: 930 Block Manitou Ave., Manitou Springs, CO
