Here's a video of a store "Meier & Frank" in downtown Portland that used to have a Santa Land on the 10th floor each year. In addition to a visit with Santa, they had this awesome hanging monorail. Well, the store was bought out by Macy's, and the 10th floor is now part of a hotel...so no more Santa Land, sadly. I'm happy to say my kids got the chance to ride the monorail each year until it closed.
Meier & Frank had a giant old-school department store downtown that was built in 1908. A picture of the building:
Here's what it looks like today:
There's a local story that before he was a star, Clark Gable sold neckties in this store in the 20's.
