I would make this the first stop for anyone who is gluten free coming to Paris. Unfortunately I was not able to get here until the end of my trip, but once I was there I bought baguettes, croissants, pain au chocolate and much more. I went to the Rue du Grenelle location. Everything is GF and there is a small area for eating in -- pastries, quiche, burgers, etc. It is worth going out of your way for. Now I need to try their store in NYC!
