Goofy's Kitchen (all-you-can-eat character buffet for breakfast/brunch or dinner) rates differ depending on whether or not it is off-peak season or peak season, and whether or not you eat the breakfast/brunch or dinner. Dinner is more expensive that breakfast/brunch. Peak season (summer and holiday periods) is more expensive than off-peak. By those standards, the peak season dinner would be the most expensive option and off-peak breakfast would be the cheapest. I actually prefer the breakfast choices 100% more than the dinner choices anyway, which works out because it is cheaper. Right now, which is considered
off-peak because it is a non-summer and non-holiday time, the breakfast would be $32.21 per adult, and that price INCLUDES tax and tip (the servers bring your drinks). Not sure about the kids' prices. Storytellers breakfast buffet is not too much cheaper than that, and the characters are ONLY out for breakfast at Storytellers, not dinner, whereas Goofy's has characters for every meal.
If you were to eat at Goofy's for dinner during off-peak times of year, like now, it would probably be about $5 or $6 more than the breakfast, so about $37 per adult, approximately. As far as I know, I think (could be wrong) that the other character buffets have prices close to the Goofy's buffet. I think Goofy's is worth it because there is SO much to choose from that eveyone can be satisfied, and there are characters at every meal. Of course, if you have
AAA or an AP, you can get a discount on the price, which comes in handy!
The earliest seating for Goofy's is 7:00 a.m., so it doesn't interfere with precious park time. I think they seat all the way up until 11:30 a.m. or so, then take a break to prepare the dinner food, then reopen around 5 p.m. or so, roughly.
