OK, folks, here's another of my ideas, and YOU get to decide if it's any good.
First a little back-story. I've been blessed with the opportunity to spend several summers (5 weeks at a time) in Spoleto, Italy, playing in a music festival there. As you can imagine, one of the wonderful things about being there is the food. You may or may not be aware of this, but food varies a lot from region to region within a country like Italy. Each region's cuisine depends greatly on the ingredients that are available locally. In Spoleto, for example, there are truffles which are harvested locally that show up in various dishes. Also, the olive oil and tomatoes give local dishes a flavor that I've never experienced in an American "Italian" restaurant.
Another thing that makes the dining experience there unique is that the menu is structured differently. You pay a cover charge up front ("pan e coperto"), and dishes are organized into sections like Primi Piati ("first course"), Secondi Piati ("second course"), Formaggi (cheeses) and Dolci (sweets). The primi piati are typically pastas and risotto dishes, while the secondi are meats. You don't order one combined plate with say, steak and mashed potatoes and green beans all in one place.
I've always fantasized about how insanely I would enjoy walking into an Italian restaurant here in the states that was EXACTLY like walking into one in Italy (short of needing Lira or Euros), i.e. with NO attempt made to cater to American tastes or expectations. What I mean is, the waiters don't speak English, or at the very most only a smattering of it. The items on the menu are organized exactly like they would be on a normal, Italian menu and are presented in Italian only. You don't get tap water unless you ask for it, and it doesn't have ice in it. BUT, you do get authentic recipes and ingredients from ONE PARTICULAR PLACE in Italy (in this case, I'm thinking of Spoleto) so that it's like you're really there.
Thing is, if done right, and the decor were authentic, it would be (for me at least) a hilariously fun adventure to eat there! It would be like going to Italy without having to get on a plane and you'd have to bring a phrase book just to order dinner! But then you'd get to eat lentil soup from an edible bowl like you can at Il Pentagramma in Spoleto. Or fresh agnolotti that's to die for like they serve at Trattoria Pecchiarda.
There's a reason you don't see restaurants like this here in the states. People don't want the hassle, they want things the way they're used to, and they certainly don't want to feel like a foreigner in their own country. Or would they, maybe? Thing is, there are some people like me who would really enjoy the fresh air. Think of it as a truly themed dining experience.
SO HERE'S MY QUESTION FOR YOU: Would you enjoy a restaurant like this if each country pavilion at Epcot had one? For me it would be like the inner sanctum of each country, the place where the hard-core virtual travellers would go.
