Are you sure you didn't have the tasting, rather than the tour?
If not, I'm confused, since the tour is $225, and then the wines are said to be nearly as much as the meal, so with tip, that would put it just about at $500 a person. Even with zero wine, it'd be $270 with service.
I am 100% positive everyone had the tour. Dinner took SIX HOURS.
I am less positive about the pricing, but I remember a number that started with a "3", and I remember thinking "I am surprised that this is not the most expensive meal in Chicago". (I meant to communicate, "200 less than 500". Sorry!)
