On my first day walking around in Paris, I discovered this patisserie. I went to the Boutique Segur location. You can visit the website for more information at Patisserie Sadaharu Aoki. They sell a verity of pastries but mostly chocolate based. I purchased 2 small items in the photo. The small cake Gateau Citron would have paired well with tea. The small Chocoron Cafe would have paired well with some milk. If you are in the area on your way Eiffel Tower and you love chocolate, check this place out.
