I am a fan of Jean-Paul Hevin. I had the 'pomme de terre' (I think) at the 231 r. st honore shop, which was marzipan around a chocolatey centre. I got that due to a mix-up of labels- I don't really like marzipan. But this particular dessert was full of interesting flavours. The milk chocolate bar was the best I have tasted, better than L'Artisan du Chocolat (London), Bernachon (Lyon) and Maison du Chocolat (Paris). I went to a Herme store but I there was a queue and because I had eaten so many pastries (and macaroons from G. Mulot) I decided not to wait... I too thought Constant was some way off the pace although I doubt I had a 'signature' creation (I can't remember what I had). The store was indeed drab but not dead. Where is Chaudun?
