We had an interesting eating experience last month in Spain. We polled up at a rural hotel and the owner said I will book you in to a restaurant in next village.
When we arrived it looked like any hock village cafe bar. Owner came over and said what do you fancy? Is there a menu.? No. What do you fancy? Fish, meat? We settled fpr beef. Bottle of wine which came with a very nice tapas ( free) . Dessert was delicious too. No prices! It was one of the nicest meals we had for ages. 84 euros for two. We think he was a Michelin star type chef that had down sized for an easy life.
Theres a place in France called La Lauzetane (possibly spelt wrong...) - magnificent, outnin the mountains. Owner just does a fixed menu every day, will accommodate you if you have allergies etc but otherwise "tomight its fish" or whatever.
I love it, and it must be better than having mounds of unused food sitting about every night just in case.
