There are some easy ways to assimilate in this city: wear black, actually wait for the little green man to light up before crossing the street, and know what people are talking about when they mention Hamy Café. This popular spot serves the most delicious (and affordable) Vietnamese food in the city, where not ordering the curry chalked up on the specials board is more sinful than anything you’ll get up to in Berghain. The inside is small and cramped, while the outside area, sat on the busy Hasenheide road, offers lots of seating. You’ll still have to queue and cram yourself on a wooden bench with several other people, knocking elbows over huge portions for just €6.90. If you want to score some serious popularity points, bring your friends here on a summer evening after watching the sun set over nearby Tempelhof.
