The place known as Zott's has been around as long as I can remember (about 1956, to be exact). The historical marker plaque reads
"This structure, built by Felix Buelna in the 1850s, served as a gambling retreat and meeting place for Mexican-Californios. It was strategically located on the earliest trail used both by rancheros and American settlers crossing the peninsula to the coast. Acquired by an American in 1868, it has continued to serve under various names as a roadhouse and saloon.
Registered Landmark No. 825"
My grandfather probably drank there as a college student; my father did too (he had a motorcycle!), and I did. Our last big family get-together was there.
It's a beer garden with a small menu. I'm not much on the burgers (some folk say they are good, some disagree). I prefer the chili, and the salami and cheese isn't bad. Sunday afternoon at Zott's is a tradition.
Back in the late 1970s and 1980s, there was an annual race from the late, lamented Peanut Farm on Canada Road in Woodside to the Alpine Inn: Nuts to Zott's. A foot race, a running race, not a bicycle race or car race.
Here's more on the history:
