Ctrip[1] names it 宝牛火锅鲜活牛肉(茶山时代荟店), shops 137-142 of 时代荟. Property sites say 时代荟 (Antai Rd/Chashan South Rd) was completed in 2017 as residential with ground-floor shops, so the store likely opened 2018 or later; no tenant or store opening report found. Low confidence. Note the input 'Times Hui' is 时代荟. Estimated: 2018 is a best estimate and 2018-12-31 is used only as a period-end sorting date, not a confirmed opening day.
Beef hotpot at the Chashan Times Hui branch, with published selections of hand-cut beef, beef balls and fresh shrimp paste. This is the Chashan branch; other BaoNiu branches’ menus and promotions are excluded.
