I am at ORD two or three times most every week and I like the United clubs at ORD. As HNL already stated, the temporary C club is not very good but the B6 and B18 clubs are both nice. Even the T2 club at F9 is nice except they do not have draft beer. B6 is an easy walk through the tunnel to get to C concourse. I believe the new C club is due to open soon. I find the staff friendly and helpful and they have improved the free drink offerings. The food overall is so so.
