A working smartphone for fact-checking will be helpful when bringing your children — or recent arrivals — to this Richmond cafe, whose celebrity burger menu dates back to the days when the Examiner was known as the afternoon paper and Willie Brown was still Da Assemblyman. Who's Herb Caen (a patty topped with Monterey Jack)? That's easy. What about Milton Marks Jr. (alfalfa sprouts and blue cheese dressing)? If you weren't here when the state senator was in his prime, a minute with Wikipedia may be necessary. We Weekly staffers cover food for a living, and even we had to look up restaurant critic Jack Shelton (San Marino chile sauce), who died in 1984. And your kids will probably guess Carol Doda's claim to fame if they order her namesake burger — two side-by-side patties, each topped with an olive.
