Thanh Nien Restaurant is one of my favorite places to meet with friends when I am in District 1. It is actually a very popular restaurant with the Vietnamese but little known with Western Expats. It sits next to the Trung Nguyen Coffee located opposite of Diamond Plaza.
The service and food is not bad but what I really liked about Thanh Nien is that is is quiet. You can meet friends and no worry about the blaring music prevalent in the other popular coffee shops these days in Saigon.
Thanh Nien Restaurant is located on 35 Hai Ba Trung street in District 1 just opposite of the Korean restaurant.
