A BOSS直聘 snippet gives 东莞市石龙蚝哥蚬嫂饮食店 (a Shilong-named single-shop entity) as established 2017-11-09, which is the best venue-level bound found. Caveat: Douyin posts from Jan and Jul 2025 mention a '石龙分店' / shop open 'three months', so the 183 Zhongshan East Rd store could be a later relocation or new branch; low confidence. Estimated: 2017-11 is a best estimate and 2017-11-30 is used only as a period-end sorting date, not a confirmed opening day.[1]
