This is THE (and only?) place to go for Sichuanese cuisine in CDMX. Was on a family vacation here…read moreand my family has historically only gone 1-2 days without needing to eat Chinese, with this trip as no exception. This place came up on almost every blog heralding the few good Chinese places in town (there's a lot of Korean places, from the way immigration came about). Almost all the customers were Chinese, most of the front desk speaks it, they were playing CCTV10 on mute in the background, you get hot tea for free...
My family is extremely picky about Chinese food and we've already been back twice. Things I would recommend: what I think is the twice-cooked pork with peppers, the cauliflower, the crawfish, the cold chicken, the cold beef "leftovers" (the body parts Westerners don't usually eat but I promise are really good).
