Nice!!! You tried the har how and sui mai. They're the two most popular dim sum. The other one worth trying is cheung fan or steamed rice rolls. It's a thin sheet of pastry sheet with filling rolled inside. My favourite is prawn filling but you can also get minced beef or char sui ( roasted pork) filling.
Yeah we really enjoyed it all. I'll definitely have to try the cheung fan next time. That sounds really good. I'll definitely be going again at some point in the future.
