Our last meal in Beijing was 涮肉 (typically mutton shabu shabu), and we wanted to try the 老北京铜锅 which is a traditional bronze hotpot with charcoal inside and a trench of water at the rim for shabu-ing the meat.
We found one near our hotel that looked quite traditional (because it’s housed in an old traditionally-looking building which we later realized was what the name of the restaurant 四牌楼 referred to) and had a few customers and has the words 百年老店 (which meant that it was a time-tested brand and literally around for 100 years), so we figured it should not be too bad.
Of course, there were also many restaurants that claimed to be 百年老店 or 老字号 as we had found out in this trip, haha.
