I don't know how reliable the info is, but someone posted on another thread that lunch is baked chicken, deli meat, breads, salads, mashed potatoes, oven roated potatoes, and more. Breakfast will almost certainly be standard breakfast fare like at most other character breakfasts.
ETA: As soon as I posted I read this on another group as a member called Disney Dining and asked about the menu:
Breakfast is from 8:00 to 11:10 for ADR's with traditional buffet servings: eggs, frittatas, potates, bacon, sausage, assorted melons, assorted pastries, Mickey waffles. Lunch is from 11:40 to 2:25 and consists of various salads and greens, deli meats and cheeses, pot roast, roasted chicken, herb crusted salmon, sliced roasted turkey, potatoes, pasta creations, stuffing with cranberries, ice cream, brownies and various cookies / cakes. Menu sounds pretty similar to Crystal Palace and Chef Mickey's from previous experience.
