One of the stops on the tour is not a chocolate shop - it's Aux Merveilleux de Fred. Merveilleux appear to be a couple of meringues with a glob of cream between then rolled in various shavings.
A coffee one and a chocolate one.
Fred's also sells raisin cramiques.
Leonidas takes claim to the Manon - coffee buttercream with a hazelnut.
Corné does them one better with a coffee flavoured fondant coating - they claimed to be the only one making them - when I mentioned that I had seen them in several other shops they seemed genuinely surprised. There's however had an excellent buttercream.
Mary's said the Mary and the salted Breton caramel were their two best.
Neuhaus developed these for a world's fair I believe he said - so one of their newer items and a good seller. It's a roll of nougatine with a filling. One of these is coffee apparently.
Did get some of the macaron and they are indeed good and indeed fragile.
My little bag of lokum.
