  昆明一颗印餐饮有限责任公司 was registered 2002-09-28 at 景星街吉祥巷18、19号, the same courtyard address, so the restaurant most likely opened around autumn 2002 (company-registration proxy); this tightens the earlier 2014 upper bound. The building itself dates to the Qing era. Estimated: 2002-09 is a best estimate and 2002-09-30 is used only as a period-end sorting date, not a confirmed opening day.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
