Was this the one that's only visible one day a year on Mickey's birthday?
Add me as another who enjoyed this lunch as a solo. I had a built in audience to talk with.
Yes, he said he didn't believe it, but was surprised that so many people were in there, he felt it was the Internet for you
When we ate at BOG we mentioned that, and our server said that an Imagineer told all of them and they went to check it out...
Mostly the Hidden Mickey's are mentioned somewhere on the Internet - but he talked about the story that they like to tell, and how they like things to "fit" the story. For instance, moving Dumbo, the story is the circus, so they know monkeys are part of it, and when you walk around you can see peanuts embedded in the walkway - but, if a monkey is riding on the elephant, and spots a banana, he's going to jump off (footprints) and eat that banana and throw the peel away (embedded) then get back on the elephant. We could not find the hidden banana peel, we asked a couple of CM's and they didn't know what we were talking about.
Also around the 7 Mine Train there are tracks, and horse shoes, you may spot a hidden Mickey.
