Ho Chi Minh City's drinking culture runs from pavement plastic-stool bia hoi (draught beer) at 10,000 đồng a glass to rooftop cocktail bars with views over the river. The backpacker district (Bui Vien and the streets around Pham Ngu Lao) concentrates the budget end; Dong Khoi and Lam Son Square have the upmarket historic bars; District 3 has the expat café scene. Vietnamese coffee culture is in a category of its own: strong robusta over ice, slow-dripped through a phin filter, drunk on a plastic stool on the pavement at any hour.
