This is a great little food stand that is built into the exterior of the Cafe de la Place. While…read morethe Cafe de la Place is fairly boring and expensive (typical tourist trap brasserie) this small vendor is a treasure.
The owner/chef is very proud of his operation and prepares crepes and sandwiches before your eyes as you wait with a selection of very fresh ingredients. If you want avocado and fig in your sandwich, well, he will cut them up for you from a whole fruit! Maybe don't try to change your order too much because the chef has a very clear idea about what ingredients go well together :)
The crepes are quite traditional in terms of the selection of toppings of ham, cured ham, cheese, mushrooms, and egg... But they do not fail to please the taste-buds. The sandwiches are more exotic with choices like fresh mozzarella di buffala and roquette/arugula and on a fresh baguette they are delicious and filling.
Crepes are from 3.5-6.5 euros and sandwiches are 5-7 euros so its a great deal if you feel like avoiding the cantine or a McDonald's...or like avoiding to pay 6 euros for a Coca Cola in the Cafe de la Place next door (how much would a sandwich cost???). However, the cafe (if they are not too busy) will probably let you eat a crepe/sandwich at one of their outdoor tables if you buy a drink from them (but be warned, the crepe might be the cheaper portion of your meal...)
Bring cash and enjoy one of the best crepe stands in Paris!
