Here is my thread with 2011 prices listed, as received from Disney Dining. These prices were loaded into the computer in January 2011, so they should be current for whole year, as Disney raises prices in January. But, sometimes Disney unexpectedly does change prices, so always best to call, if budget is an issue.
Prices listed are peak season (OP doesn't say when trip is), and tax included. For non-peak, just deduct $4.00 plus tax/adult and $2.00 plus tax/child from the listed prices.
