OK I jus got back. I mean literally. I haven't even been home for an hour yet. Anyway, here is what I found out. In the food court at POP, all the way to the right side, there is an ethnic style restaurant. According to the workers there, they are the only ones that will have the egg substitute or even just egg whites (without the yolks). It is something that you will have to specify when ordering, of course but that is the report. I didn't actually have the opportunity to sample the fare for breakfast this time at POP. We were always trying to beat the crowds to the parks and just never had the time.
Hope that helps!
