If you're looking for some decently priced (loosely used given the tourist prices here) and quick…read morefood, this is probably your best option. It's located on the way up (or down in our case) from the Abbey. They have crepes, galettes, sandwiches, fries, and soda. We got both the sweet and savory crepe and a sandwich. Nothing to write home about, but it filled our stomachs and gave us energy to get back on the bus back to Paris that evening. They have dining in a small section upstairs and some seating downstairs, and they ask you to wait until you're called to come get your food so it doesn't hold up the line since it's a small entryway. I think they had a bathroom, but I didn't use it. Like I said, don't except much from the food here, my sandwich had maybe a slice of cheese and one tomato in it and the rest was all bread/baguette. It'll give you some quick energy and there is a gelato shop not too far if you want something cooler during the hotter months.
