Village-style Chinese cuisine in the Viaducto district, far south and east of the typical tourist venues in Mexico City. Waitress spoke Toisan dialect of my family, sons did the order in Mandarin. Third world service, with teacups coming to table in a bowl of boiling water. First cooked green vegetables after a week south of the border, comfort food settles the stomach. Walked around a few blocks, but didn't find strong evidence of Chinatown vitality. (Jing Teng, Viaducto Piedad, Mexico City) 20191224
