It’s difficult to choose the best "Crêperie", there are so many; I think in the centre of Quimper there is the highest density of crêperies for square metre.
Place au Beurre in Quimper is a pretty charming square, hidden in the centre of the town, among tiny old streets.
This square is known and appreciated also for the fact that the location puts together several crêperies where to taste the traditional delicious savoury or sweet Breton crêpes.

Maybe it would a good idea to try more than only one crêpe in different places…just to find the best one.
