You may know that I'm the author of the Unofficial Dining Guide to Walt Disney World 2007, a book with current menus and prices at WDW restaurants. As a result, I'm doing my utmost to stay plugged in to the happenings at WDW eateries.
There's always a lot going on. At DAK's Asia, you have Ying and Yak replacing the fries shop and the quick service Asian food. At DtD, Landry's is opening T-Rex, a concept I'm really looking forward to (they are being coy about where, exactly, the building is to go. Or if it's replacing something already there). At the Swan, Il Mulino will soon open, replacing an older table service concept named Palio.
Rehabs continue all the time. Teppanyaki in Japan is down for four months this spring, as is 1900 Park Fare at the Grand Floridian this fall.
The Concourse Steakhouse will close this spring, and Chef Mickey will expand. Meanwhile, the food court downstairs at the Contemporary will be removed, and an Asian Fusion place named the Wave will take its place. I'm looking forward to that one.
Here's a minor decline by degrees related to restaurants: they used to give away a free lithograph when you ate inside Cinderella's castle for dinner (lunch was a plastic wand for girls or sword for boys). Now they just give out the wand or sword for all meals. Le sigh.
