Travelling to a few places in France and Italy and would love some help

[TheEngineer]

A group of my friends and I (totaly five guys) will be travelling to the following locations at the end of July.

(1) Champagne
(2) Burgundy/Dijon
(3) Bordeaux
(4) Cognac/Jarnac
(5) Piedmont

I would love to have some suggestions as to where to go for lunches and dinners in and around the wineries. I've got many of the winery visit worked out but would still ove some suggestions for easy to access (i.e. easy reservations) but would really like to get some interesting side sights to visit too. Would anyone suggest visiting a cooperage? Cheese shop, etc,...whatever would be in the area of the wineries which is our focus would be much appreciated. We are getting close and the gang is rather excited!!!

Many thanks in advance!
