a big park, with a concession booth, on the east side of a major street. It had two large slides, (side-by-side, so kids could race)

When I was a kid there there was a place on the corner of La Palma & Magnolia (south-east corner) that had a huge slide (you could race your friends down), trampolines, a miniature golf course and Chubby Burger (I used to love playing the KISS Pinball machine there). Could this be the place? It wasn't a park, but matches your description.
