Lyon is know for certain foods. The restaurants it's famous for are bouchons. They're traditional and serve, depending on the season, a lot of game and sausages. Many serve at family style tables, where you share a table with whomever is there. There is an area where all the restaurants call themselves bouchons, below the basilica near the river. My Airbnb host, who didn't speak English, sent me to that area but none looked particularly appealing - more like tourist places that call themselves bouchons than true traditional places.
I asked a local for a restaurant recommendation. They didn't send me to a bouchon. They recommended a restaurant. I went right when they opened hoping I'd get a seat. I lucked out only because an Australian behind me had a reservation. His wife wasn't feeling well and skipped dinner - so he asked if I wanted to join him. The food was great and it was nice to have conversation. I'm horrible at remembering names of places. It was a short walk across the river from where the "bouchons" were located.
Afterward, I stopped at a pub, between the rivers, for a beer and to watch a football match. I was pleasantly surprised how friendly everyone was toward a random American stranger. Hopefully you will experience that.
To answer Bob's earlier question, my favorite would be a courser place that hasn't been remodeled in 150 years (or more) that serves good quality, not fancy, traditional French food. Extra points for a down to Earth crowd who aren't dressed up. I don't mind if it's a bar, as long as the food is good.
