Did you know that mustard is a huge thing in France? Many French people use it with meat, for instance eating with steak like Maurice and you can find all sorts of areas that make their own. Maille Mustard is one of the most famous mustards. You can find it in the States but it tastes different here, usually with a stronger taste. Right across the street from the Madeleine church is a Maille Mustard boutique, a rather elegant place.
Next door was a chocolate shop-I think those giant eggs are supposed to be cows in an artistic way. There were metal pipes inside which lined up exactly with the columns on the church which I thought was great.
