Hi- I just clicked the link provided, and the seats are $125 a piece, but that includes food and strolling musicians up on the roof. It also states that Michael Pollan is only going to be part of the program in the auditorium. They also have some music performances too during the one and a half hour performance in the auditorium.. The program is sponsored by Chicago Charitable Trust. As much as I like Michael Pollan, the price of tickets is a little steep for me. I'll be coming back from jazzfest in New Orleans that day anyway.
