This cute little traditional restaurant sits in the Latin Quarter of Paris, just west of the Rue Mouffetard. I happened upon it many years ago, and I remember the food was good and the access was also surprisingly good, especially for those days. There is a ramp running alongside which takes you up to the open-air front section. This is the nicest spot, on a balmy evening, although you might have to book to guarantee a good one.
I checked up recently, and I was pretty pleased to see that it’s still there. I must go again one day.
