Mexico - As good as you can get in a really good Mexican restaurant. But has the best environment, especially for romantic dinner. Be sure to ask for a seat on the water. Wait for it extra if you have too, worth it.
Norway - Don't even think about it, terrible.
China - As good as you can get in any good Chinese restaurant, nothing special. Some people love it, but prolly the same people that eat a lot of takeout Chinese and not the good stuff.
Germany - Great food, very authentic and great entertainment, dancing and scenery. Good for groups of adults who want to have fun. The food they serve is not easy to find the way they prepare it in America, very German style. Beer is served by the liter as it should be everywhere.
Italy - Again, as good as you can get in any fine Italian restaurant. It's good, but you pay for it. There are enough good Italian restaurants in USA that will stack up to this place.
USA - Crap. Wonder when they'll put a real Americana type restaurant, at the very least like Liberty Tree Tavern in MK. It's almost embarrassing what they serve compared to the other countries. There is no question why USA is fattest countryin the world and what USA represents only confirms it. Just keep walking unless you need to use the bathroom, seeing that it's the halfway point in the countries.
Japan - Yaki is as good as any other Jap steakhouse like BeniHana's, only better environment. Matsu's sushi has small portions of sushi. However best place to eat and watch fireworks at 9 in the Matsu lounge sushi bar. I think the sushi at Matsu is actually one of the worst sushi places I've been, as compared to a lot of places in NYC. But if you are drinking some sake and eating your sushi at 9 pm and have front window seat, you forget how bad it is real quick.
Morocco - The most original food and authentic. The food is outstanding if you like middle eastern food. Has great entertainment, but kids prolly won't like it.
France - Again, a good French restaurant. Open your yellow pages and find any 3-4 star and you'll have the same. I think the most overrated of all Epcot restaurants.
England - Rose and Crown, the food is not bad and limited menu, but better then Raglan Road. The best watering hole in all of WDW for sure. Seems like they are more interested in the beer crowd, and will feed them since they seem to stick around for hours upon end, I'm one of them. I only eat there because I usually don't want to lose my seat. I've literally stayed in there from open to close on several accounts. Especially when starting my drinking around the world from right to left.
Canada - The second most overrated restaurant in Epcot. Eat at Ruth Chris' or some other "better then Outback" steakhouse and you'll be just as better off. The cheese soup is good, but buy one to go for lunch or something.
So my 2 top favs are Germany and Morrocco if you want something you can't get somewhere else. Mexico is really good and kids like the environment as well, especially if your sitting on the water. The rest, like I said, open the Yellow Pages when your at home and you'll find better. So you should at least start with these 2 as suggestions. But then again, I'm not a picky eater, I eat everything god put on this earth to consume and then some.
