I was up there the other week apartment hunting and scoping out the area.
Check out Manitou Springs, just outside the Springs. It has a fun little downtown area with lots of local restaurants, shops, etc. I ate at their brewery which had excellent food. I always recommend brewery food. Generally good value for the money. There are a lot around the Springs.
I second the Zoo. Supposed to be excellent and who doesn't like a good zoo.
I've never been to a Santa's Workshop, but they have in the Springs just like in College Station.
