Yes, they have a ton of those whether it be kiosks or regular stores. Also not all of them are Chinese, the King of Prussia mall has very diverse shops and they all do things a little different. Go on the King of Prussia mall's website and do some research, I'm sure you'll find what you're looking for. :)
I am not exactly sure what y'all might mean. But what I can think of is Custom Creations. I also can't think where exactly it is, but they do have interactive maps there. I am not sure if it a kiosk/booth or not. I don't see many Asian workers at kiosks as well. Good luck. Also, today, Christmas Eve, the store I mentioned is only open until 6pm.
