Look at the dates on the menus you are checking at AllEars. The places you referenced were updated this month and most likely reflect the $5 ridiculous peak season surcharge. Some of them with odd ending decimals, like Biergarten at 39.40 include tax. So figure that if you don't go during one of Disney's designated peak times, Biergarten for dinner really costs 31.99 which sounds like a more normal price for this meal. Same for Crystal Palace which would then be 21.99 for breakfast as well.
Quick Edit: Steve just posted an updated list that shows when these extra surcharges are in place http://www.wdwmagic.com/holiday-dining-dates.htm
Thanks, Evan. The way I read those menu prices it seemed that was the regular price and holiday pricing was additional to what was stated. I think I'll call WDW Dine to check on that.
Even if the regular prices were $4 less, Chef Mickey's is one we have become turned off to because of the stupid price. $30 for breakfast is just dumb. Buffet or not. D-U-M-B. That's definitely a clear slap in the face..."We can charge it because people will pay it." Guess what? I won't. Someone else can take that one dry. Won't be me.
