Well, somewhere in Hồ Chí Minh City a contract quietly expired and the Trung Nguyên at 1 Trần Hưng Đạo in District 1 is no more. The love heart on the front door and Trung Nguyên paraphernalia have been removed.
I now reside at 603 Trần Hưng Đạo, on the edge of District 1. Unfortunately they don't do food.
