No, sorry... Pooh and friends left Artist's Point back in May of 2001. Artist's Point no longer serves breakfast.
You may find the Pooh characters at Crystal Palace in the Magic Kingdom for all meals during the day, and at the 1900 Park Faire breakfast, along with Alice in Wonderland and Mary Poppins.
I am sure that you will be pleased with either of these breakfasts. Personally, we prefer the one at 1900 Park Faire. The food, service and character interaction is wonderful!
