For tourists, everything that happens in Hanoi happens in the backpacker cafés. Anything that can be had, rented, chartered, borrowed, exchanged, and bought can be obtained or arranged in them. They sneak tourists illegally across the border into China for day jaunts, book hotel rooms, lodge people in-house, serve decent Western food, sell traveling supplies, fresh baguettes, and Laughing Cow cheese, which is the staple travel food for foreigners who fear stomach bugs. They book anything. Legal, illegal. You got the dollars, they can find your pleasure.
