Honolulu Coffee Shop (Wan Chai)

Honolulu Coffee Shop has run 24 hours since 1940, making it Hong Kong's longest-operating late-night institution. Its pineapple buns with a crispy sugar crust and fluffy interior slathered with cold butter are freshly baked every 30 minutes. The Hong Kong milk tea, using condensed milk, is 15% sweeter than the typical rival, while the hot soup noodles offer warmth at any hour. Late-night diners enjoy 25% larger portions than daytime servings. Price: HKD 25-60.
