Maxim's Palace
For dim sum in Hong Kong, Maxim's Palace is as classic as it gets.
Another Hong Kong classic is milk tea, AKA super strong tea with evaporated or condensed milk. And at some point in your trip, you should get to Tsui Wah for a cup. There are locations all over Hong Kong, and you can pair that milk tea with a toasted bun also smothered in condensed milk. Many of the outlets are open 24 hours, so you could do this for breakfast, afternoon tea, on your way home from a night out - really, whenever you want.
