I will tell you now: this one might be tricky. Yes, they are crepes, but where? I will give out another clue after I get 10 incorrect guesses (or when I think it's necessary, which ever comes first). Good luck.
Update: Okay, I can see this one's going to be tough. So here's not one, but three crucial hints.
1. The restaurant is not known for the crepes.
2. It is famous for another delicacy.
3. There are two of them in the same city.
Again, one guess per comment per user, until I give out another hint.
