I have found memories of this diner, but more specifically of the mini golf course hidden behind it. The 18-hole course is made up of giant diner food. While it hasn't been as meticulously maintained in recent years, it's still a site to see.
The golf course was designed by artist Jerry Berta who at one time owned Rosie's Diner and use one dining car as an art gallery.
The course is still playable, and I HIGHLY recommend.
