On to those with most favored crêperie status:
La Crêpe Rit du Clown
I like this place because they have a choose your own salad option with tons of toppings, which is great if you don't have a crêpe-lover dining with you. Believe it or not, there are some people who prefer salads to crêpes. I have even met someone who doesn't like chocolate, but that is a whole 'nother story. They also have a dinner menu, which they recently increased to ~15€ from only ~11€ (grr): cocktail + galette + dessert crêpe + cider. The only drawback is if you get relegated to the windowless basement, which can be drafty, means slower service, and just isn't as cute as the main floor.

I have a fondness for this place because I used to lunch there quite frequently. It has a bright artsy decor, and a ~9€ lunch menu: galette + dessert crêpe + a glass of cider. No dinner menu. Cool upstairs alcove. Nothing really sets it apart from the other crêperies flanking it (the boat one and the art one - both just fine) except for the interior, but I guess this is as valid a reason as any to prefer it over them.

This place is right across the street from one of my favorite cafés, La Pharmacie. It has multiple menus, with varying options and courses, but I can't recall the prices or the details. I believe the lunch menu is also around 9€, and the most expensive dinner menu is 15€. The menus might finally be up on the website by the time you are reading this so check it out. The seating can be cramped but the service is friendly and they also have daily specials that are more elaborate than one might expect from a crêperie.

Open everyday except Monday lunch
I also feel obligated to mention somewhere I have never been, Crêperie Ty near Montparnasse, because I have gotten outstanding recommendations for it from multiple sources. The bar owner around the corner from where I live swears by their salted caramel crêpes.
Anyone else have any recommendations?
