Hanoi Train Street (Nguyễn Thái Học) is a narrow railway attraction in the middle of Hanoi's Old Quarter, where trains pass within tens of centimeters of houses and cafes. At the colorful cafes along both sides of the track, you must order a beer to sit and wait for the train. When a train passes, the cafes clear their tables and people step aside, and crowds gather near the operating times. Vendors push their sales aggressively.
