"Sioux Fan", from earlier in the thread, usually organizes the alumni events in Colorado Springs and sometimes Denver, I talked to her last night and there's nothing official from the Alumni assoc going on, the lead time to get things rolling for AA support is like 3 months.
So, if you are a Sioux fan in COS on Friday, go to Carrabbas. We'll all be there in green and white.
As far as other bars/restaurants around the World Arena area, there is a Chili's very close by and up the road a little is a Red Robin, Chipotle, On the Border, Panera Bread, etc.
PS If you want to try some good tex-mex while you are here, go to The Loop (Manitou Springs) or Amanda's Fonda. Shopping for Touristy items? Old Colorado City, Manitou Springs, Garden of the Gods Trading Post. Just want to get some fresh air, or take a mountain drive? Hit Garden of the Gods, or drive up to Cripple Creek for a little gambling. Need more to do, just ask.
