Pac Place fly him in from Canada from memory. He is very authentic. If you have a platinum Amex card last year you could get into the house for free etc. They take photos, and you can take your own photos as well. Yes, they did give some lindt chocolates as presents.
Not sure if they are doing it this year, as they haven't constructed anything in the mall as yet.
This was the only one we found last year, outside of a santa at the Matilda hospital carols. It wasn't quite the same "quality" of Santa.
