The newest Mamie Clafoutis on the Promenade Fleury is very nicely renovated -- lots of light, lots of space, not a lot of seating for its size but no problem finding a seat when I've been there so far. It's a really nice space to meet a friend for lunch or read a book with a cup of tea.
The food, at least on the sweets side, isn't that great, and the espresso drinks aren't up to snuff either, but at least they offer soy milk (unlike other establishments on the Promenade Fleury which do have excellent coffee and baked goods). I'm not a fan of the food at other Mamie Clafoutis locations either, but if you are, you'll like this location just as much for the food and even more for the lovely atmosphere.
