The Boz: Yep, and only one in Chicago on the lake.
It turns out that if you do a Google Map search for The Cheesecake Factory in Chicago, there is only 1 location, and that is the on the lake location that The Boz mentions...
But if you go to The Cheesecake Factory website and look for locations, there are actually 6 locations in the Chicago area and 1 of them is located in (drumroll please...) Schaumburg, IL, just 1 mile down the street from good old Value City Furniture, where Christopher Mitchell shops.
With a Dairy Queen, a Hyperbaric Oxygen place, Portillo's, Value City Furniture and now The Cheesecake Factory all within 5 minutes of each other, this is getting to be more than just a coincidence.
My confidence is now pretty high that Christopher Mitchell is in or near Schaumburg, IL.
