Nice. While I no longer commute to work, it's also a good place for people riding their bikes into the Loop on an occasional basis I think. At least it used to be. I don't know what their storage/membership constraints are anymore. I'm sure they have changed over the years.
It is under new management. You can get a day pass.
The annual membership includes a locker. I don't know what they will do when all of the lockers are taken and they have people who want annual memberships. Previously the fee for a locker was separate from fee for access.
At this point there are plenty of lockers available.
