Thanks for the link I suppose it is quite complete. I actually know Lyon very well having lived there for a year and in general going for a few days 2-3 times a year. I guess my only question would be suggestions for ethnic food, or any really new places on the dining scene as I haven't been to Lyon (with time to dine out) in about 18 months. Of the list in that large post I have eaten at about 80% of the places so perhaps there aren't so many surprises...
Lucky you, getting to spend FIVE weeks in my favorite city! As DaTulip said, there are already tons of recommendations for Lyon here in this forum. After you've checked some of them out, come back with more specific questions.
I know I'll (and others, as well) will be glad to answer them.
There are quite a number of recent threads on Lyon. Here is one that I think has quite a lot of information, but there were at least 10 others when I searched just now:
Hopefully you can find some good information there as a starting point.
