Able to spend time in Lyon for lunch and since this is a gastronomical mecca... What have or would you do for lunch in Lyon end of June?
The Paul Bocuse indoor market would certainly offer some good options:
The market linked above is a short walk from Lyon Part-Dieu train station, if that's how you'll arrive in the city (but it's not the only train station).
What day of the week are you going. If it's a weekday, there are some places near the Palais de Justice (tram stop "Palais de Justice") which do really good lunches for the lawyers and court staff market.
will be there on a thursday.
I highly recommend Daniel et Denise (http://www.danieletdenise.fr/en/). Charming staff and delicious food that's a slightly lighter interpretation of classic Lyonnaise cooking. We liked this restaurant so much we went 2 nights in a row. Other Lyon highlights for us: L’Ebullition and Nardone Rene Glacier for ice cream.
OK. If you go to the Palais de Justice, which is a very quick tram ride or even walk from Part Dieu station, try Bistrot du Palais or L'Ame Soeur.
If you find yourself in Vieux Lyon, Les Adrets on rue du Beouf has a fine lunch menu for around 18 €. This restaurant is recommended by both RS and by the landlady of our gite in Lyon. We had dinner there, and it was an enjoyable, true French experience (right down to the 2+ hours that dinner lasted). The food and service were wonderful.
For a true Lyonnaise specialty, have the Quenelle Brochet with sauce langoustine at Le Café des Fédérations. Here's a link to their website. Be sure to make a reservation or there's a good chance you'll be turned away - lunch or dinner. Easy to get to from the rail station by cab or Metro. Quenelle is a traditional dish originated in Lyon.
^^^ Great restaurant!^^^
