I can second the Restaurant Akershaus (in the Norway Pavillion, EPCOT Center). Excellent buffet well worth the price, and the place actually serves mead.
At all costs avoid the Whispering Canyons Inn at the Wilderness Lodge. Granted I might be speaking from a position of a former employee who is glad he's shut of the place, but I never thought the food was any good, even when I was cooking it. But then, I've grown allergic to die-stamped meals as I've become older.
