In two hours’ drive from Silicon Valley and one hour away from Yosemite National Park, CA right on the intersection of Highways 140 and 49 there’s a Happy Burger Diner in Mariposa, CA. For $4.99 extra you can have any burger made with an ostrich patty, which I enjoyed tremendously, even though ostrich meat is a bit dryer than any meat I am used to.
Also in Mariposa is the Mariposa Coffee Company. I stumbled upon them about 10 years ago and still order their coffee on a regular basis. It’s probably not far from your diner.
