An excellent tour, very informative about Tiffany glass and Chicago architecture. Also includes free voucher to the Institute of Art, worth 18$ and outstanding.
The trip was pretty good although the group size was too large (we were told that usually groups are only one half the size that ours was). That also made it very difficult to hear the docent whose voice was not that loud to begin with. This was an efficient means of seeing many of the Tiffany pieces. Also, we did not receive the free gift from Macy's as advertised.
This was an excellent tour, conducted by a knowledgable and friendly guide. I also did two other tours with the Chicago Architecture Foundation and would recommend them too. It's a great way to learn something about the character of a city that you'd never learn otherwise. I recommend very comfortable walking shoes and sun protection.
