<font color=navy>Hi Dana,
I'll give you the character meals in order of my own personal preference:
Disneyland Hotel
Goofy's Kitchen B-L-D
The food is very good - buffet, with excellent character interaction... I've seen Goofy, Pluto, Aladdin, Genie, Jasmine, Mad Hatter, etc. I've heard others compare this to Chef Mickey's at WDW. The characters visit the tables, and every now and then everyone dances in the middle of the restaurant. (PS can be made)
Disney's California Adventure
Avalon Cove L-D
We had dinner there, and one price will get you soup or salad, entree, dessert, and beverage. Ariel greets you in the foyer, and we were visited by Minnie, Goofy, and Chip and Dale - I think more characters come here. The food is good, great ambience, and in the evening you're treated to the lit-up Paradise Pier. We danced the conga with the characters --- great interaction, and the food was good here. (PS can be made)
Disneyland Park
Plaza Inn B
Buffeteria w/Pooh & Friends. The food is good here, and Pooh & friends will visit you. I'm not sure if PS can be made, but we've never needed to make it.
Paradise Pier Hotel
Practically Perfect Tea with Mary Poppins Set times
Have your choice of tea with soup, finger sandwiches, and dessert, while Mary Poppins sings and visits with you. I wouldn't call this an intense character interaction, but the atmosphere is very nice. Your party sits at a table, and Mary Poppins comes in two separate times and sings a song. She goes back out, and returns to visit with each table. Afterwards, you take pictures. I found this to be charming. (reservations with credit card)
I haven't experienced the following:
Grand Californian Hotel
Storyteller Cafe B
Breakfast with Chip & Dale. Chip and Dale greet you when you come in, and you have a choice of buffet or menu (I think). I have heard that the chipmunks do not visit each table individually.
Paradise Pier Hotel
Breakfast with Minnie B
I don't really know about this experience. Hopefully, someone else will have more info.
