Food in Panicale ?
There's a place in Panicarola, close to Panicale, which used to be very good. There's no menu and the cook prepares whatever he feels like cooking based on the ingredients he's bought that day. I remember exceptional pasta with truffles and some meat thing with mushrooms which was really special. However I last ate there about 4 years ago so can't vouch for its present quality. There's a website www.locandadelprincipato.com, see if it inspires you!
We went to that area for a holiday some years ago, and I can't remember for the life of me if we stayed in Panicale or Paciano, which are very close to each other but I've got feeling it was Paciano. I remember a few good places to eat, but this is a bit out of date, so some of these may not exist anymore.
There was a restaurant in the village itself - in the walls of the old town - it used to serve local food and was fairly up market - we had a very good meal there. I've googled both villages, but can't find any reference to it, so I don't think it is still in business.
There was a very good place just outside the village - I've googled it, and I think it must be Il Casale. It was always very busy, run by two women and delicious food. Rustic and large portions.
We had a very memorable meal in Chiusi in a place called La Solita Zuppa. It was a set menu (a few choices) and it's worth going with any recommendation he makes to go with your food - we had a lovely sweetish white wine with our starter - we would never have ordered it, but it made all the difference. It's had good reviews, but there are some very bad ones too - I've just seen some people on the Slow Travel site complaining about the service - I'm not sure went wrong there, but reviews before and after seem to be all good, and we had a lovely time.
I cannot recommend Il Casale highly enough. I ate some of the best Italian food of my life (everything is made daily from scratch, including the bread) there, and have wonderful memories of this friendly trattoria where we enjoyed an incredibly relaxing time. Entirely family-run and owned, with mother in the kitchen, daughter in the dining room and father at the register. If you happen to find it, don't pass it up!
Oh, yes. Close to Panicale, there is the small town Castiglione del Lago. Well, particularly if you enjoy good wine, I strongly reccomend you the wine bar VINOLENTO where it is possible to taste the true Umbria cooking.
Don't be in a hurry when you will be there and enjoyt this magic place.
