This is cool to hear, since we have these already in Japan, albeit Nagoya and Tokyo are the only ones I know of. It's pretty cool that they have classes there and it is a great chance to try out all their lenses to get a feel for something you are about to plop down $2000 on.
The one near me offers free intro classes on how to use the 650D, Macro, Portraits (need to bring a girl with you), and kids photography (must supply own child).
I don't think you can buy anything at the one we have in Nagoya. I don't think I've even seen a cash register.
