I haven't seen this posted anywhere else online so here's my 1978 map of Busch Gardens in Van Nuys. This is after the 1972 expansion closed and in its last year of existence.
Note that "Food For Thought" on the second page tells us that churros ("a delicious pastry treat") are available at "Busch Plaza (Novelties)", #3 on your map!
