This is a bar inside the Palais des Papes (if you go through the shop, in the back, then the entrance to that part of the Palace is free).
For 5 euros (6 euros if you want some cheese and foie gras appetizers) you will get 4 tasting of good wine corresponding to the four Bourgogne wine denominations, and a gift consisting in a metallic wine pouring pocket cup. Try the favourite wine of the seven Avignon Popes, a Grand Cru Bourgogne red wine elaborated with Pinot Noir grapes.
It is a great and didactic wine testing experience.
