My personal highlight: Crêpe with pears, walnuts and roquefort. Simple tasty.
If I would like to have a real good crêpe with some fancy ingredients the place I go is Chez Babette. My favorite crêpe is the one with Roquefort cheese, pears and walnuts, a real tasteful combination of flavors! The bistrot is located at Idaplatz, Bertastrasse 16.
