Consulting in Chicago - what gym?

I'll be spending a lot of time in Chicago during July and am wondering what gym I should use while I'm in town.

Important to me:
- auto-belays and bouldering as my schedule won't really allow for finding partners
- decent access from the train (job site is at the O'Hare end of the Blue Line)
- opens early / stays open late (crowd avoidance)
- decent cardio equipment

Any thoughts?

Brooklyn Boulders Chicago if you are downtown. Vertical Endeavors if you are in the suburbs. First Ascent is set to open soon in Logan Square area as well, but they may still be a while.
