We are stopping over for 1 day in Lyon on our way to Burgundy from Provence mainly to try regional cuisine. It happens to be Sunday so most of our first choice places seem to be closed.
The only one I could find thus far is La Gargotte (which according to yelp works sundays - can someone confirm). But we are open to your suggestions! We are yet to reserve our lodging and will do it in the proximity...
My wife is fluent in french, so lack of english is no issue.
