yes you can get it at POP. Not sure about the resturants but i was able to get soy Ice Cream from Kona and soy waffles from Hollywood and Vine so i am thinking that they would also have milk.
Yes, you can get soy at most all of the food courts. At the Poly they had not only vanilla soy milk but also strawberry and chocolate....that was very nice.
All star movies food court had it with the different flavors. I can't remember what restaurants. Some did and some didn't. Some offered to get it for us if they didn't.
