This location boasts 54,000 square feet of workout space. We missed this particular one on our recent tour, however, we have been inside various FFC gyms and they tend to be decent workout options.
This particular club isn't super convenient if you are staying in the Loop, or on the Magnificent Mile. It's a quick cab ride (or a 2-3 mile jog if the weather is nice) to get there. If you're driving your rental car, the first two hours of parking are free, then it's just $11/hour after that.
On the upside, this FFC appears more upscale than many we've toured and there is a 24-yard lap pool with 3 lanes (approx. 70 feet in length). There are also myriad classes offered, nicer than average locker-rooms and towel service, always nice for travelers. But bring your own lock for the lockers. Most important, the cardio and strength equipment is new, new, new!
First two hours of parking are free. Admission costs $30/day, but if you belong to an IHRSA club back home, it's $20. Post-workout, in the summer, consider a relaxing lounge on the roof deck.
