The oddest thing you have to try in Chicago is popcorn. Apparently there are tons of places you can get it from but the Chicago natives I met swear by Garrett’s. I got my popcorn to-go at the airport, where I got to talking with the woman in line behind me. “Garrett’s is the only popcorn I eat” she told me, and if that’s so, she’s one lucky lady. While you can choose from regular buttered or cheese, I always go for the caramel.
