Now I'm torn I was originally thinking we'd do Plaza Inn because I know they have a great Character turn out, but we read some reviews that said the food was bad. So we changed to Storyteller's because we have been told that the food was better, but if the character's aren't as good...now I don't know.
Our family likes the food at M&F, fresh fruit, excellent pastries, I had some eggs made to order, potatoes....I also had pancakes, it was all very good and tasty.

We also saw at least 8 characters (it's been a couple of years, I'd have to dig thru tons of photos to find out how many exactly), off the top of my head we saw Max (Goofy's son), Eeyore, Tigger, Alice, Mad Hatter, Cap'n Hook, Gideon, Honest John & Gepetto, Minnie, Chip & Dale...well that's 12 right there and I think there may have been more....M&Fs is the most character concentrated you will get, all other character meals have 5 or perhaps 6 characters. Even with all the characters and all the playing with them we had no problems filling our tummies with yummies.

If I were you, I'd switch back...BUT I haven't done a character meal at Storyteller's so take that into account.
What do they have for breakfast at AG?
I'm wondering if that's where we might want to have our character breakfast (so we don't miss out on precious early morning time in Fantasyland). We've done GK and Storyteller's before, and while I liked our experiences there, Chickadee might like seeing some princesses.
Bfast at AG is served family, you will get the 3 tiered plates that will have fruits, pastries and cheeses, then you will get a platter with scrambled eggs, potatoes, sausage, ham and bacon. You can get as many refills as these items as you would like, your server will be happy to bring you more as it is needed. Drinks are also brought to your table by your server, your server will also bring you refills.

The food is not great, our family prefers dining at AG for lunch or dinner. And yes, you will get 5 Princesses, you see Ariel every time at the bottom of the stairs, then you are seated and 4 more Princesses are announced and visit your table. We've seen the following Princess, not all on the same visit of course as there are more than 4 we have seen, Belle, Cinderella, Aurora, Snow White (these are the standard 4, we've seen them a lot), Pocahontas and Mulan (we've only seen them once and it was the same visit, that time we saw Pocahontas, Mulan, Snow White and I have a hard time remembering which other one we saw that time)
I've noticed that all the meals, except Minnies average 5 characters. I think that's probably what Disney schedules during a typical meal. In WDW this is usually the case as well. We have experienced most character meals at WDW and I think Akerhaus may have had 6 princesses, but all other meals usually have 5 characters.
That is why we were so surprised/amazed by Minnies. We usually have over a dozen visit during our breakfast. We get there at the first reservation of the morning. TONS of characters there to greet us! My kids usually walk to the table, arm in arm with a fuzzy friend! And I have a lot of kids!
Plus they are very generous with their time. We have never felt rushed there. I've got some terrific photos with the kids and multiple characters.
This is why we love Minnie & Friends!
