Dabao Concept is a cafe on the third floor of an apartment building on Nguyen Trai Street in District 1, Ho Chi Minh City, near the Ton That Tung intersection. The menu is simple, with coffee, soda, and slush-style smoothies. You park in the basement, then walk up a dark stairway to the third floor. It closes at 9 p.m., and it is hard to concentrate there when working on a laptop.
