Frosty Freeze was a teen hangout on Foothill Boulevard in eastern Upland across from Memorial Park. Some called it Yum Yum’s Frosty Freeze, or just Yum Yum’s. From the sign, it looks like the phrase wasn’t necessarily intended as part of the name, but I can see the appeal of calling the place Yum Yum’s.

According to a reminiscence by Shelby Garrett, the stand went up in 1950, founded by Mary Weitzel: “Teenagers went there for great hamburgers, shakes, malts and dancing.”

One habitue was future crime novelist Joseph Wambaugh, who told me a few years ago that Yum Yum’s was a favorite hangout for him and the rest of the Chaffey High crowd in the 1950s.

Mike Guerin, who grew up in Upland, took the above photo in 1981 when Frosty Freeze closed. Note the sign in the window: “We Quit. Out of Business. We Will Miss You.” (Click on the photo for a much larger view.) Guerin says: “Just found this in my files. Fast food from a family restaurant. Millie was always at the register.”

Do you remember Yum Yum’s Frosty Freeze?
