It is believed Pekin Noodle Parlor was the oldest Chinese restaurant. I had an episode on it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-x4t-ujRAg_g.html.
That is wrong. This restaurant date back to 1912. A Chinese restaurant in Oakland California date back to 1903. Another restaurant in San Francisco date back to 1911.
They have different definitions like "continuously operated", "operated in the same family", etc. If this is a topic you're interested in, I recommend reading the research paper from the UC Davis team that broke the story of Chicago Cafe -- Symbols of Survival: Finding the Oldest Chinese Restaurants in the United States (papers.ssrn.com/sol3/papers.cfm?abstract_id=4493301)
This is great. I had a restaurant a few years back and we put vintage menus on the wall as artwork. One was for the California Zephyr. This is a train ride on my itinerary. Will be great to see how the menus compare. "10000 Clouds"
