In 2010 I wrote an article about all the places you can find Snow White in Disney's California Adventure. Well, now that it's Disney California Adventure, it's time to update that article. Hollywood Land, name change aside, has remained more or less the same in terms of the Snow White references. However, there is quite a lot of Snow White to see in Buena Vista Street.
The most obvious reference is the Carthay Circle Restaurant. See my review from earlier this month.
There is another reference to Snow White inside Fiddler, Fifer, & Practical Cafe there is a bulletin board:
Snow White whose father was a vocal coach and received a casting phone call that Adriana picked up and promoted herself on.
