All the pastries I've tried are incredible. The alphabetized chocolate 'tablets' are amazing. Sandwiches: very very good. THe look and feel and service of the shop are lovely.
Maybe the best part of all was the last time I went in, I was offered slightly-broken-but-still-tasty macarons. For free! I restrained myself and took only one to go with the 6 I'd just purchased and ate it as I left.
