Din Tai Fung is a Taiwanese franchise restaurant with high-quality food. They are especially famous for their mini dumplings (Xiao Long Bao 小籠包).
Do you see the people outside this restaurant? That's during lunch time and they all wait to be seated. Don't imagine how dinner time looks like...
I've been to one in Beijing with my cousin and his wife and this one is in Taiwan. But they are also located in Australia, USA, Singapore, Japan, Korea, Malaysia, Indonesia, Thailand and other cities in China. I can't wait for them to come to Europe.
It's also easy for foreigners because their menu has pictures and is written in several languages including English.
Anyway a must-eat is the dim sum dish Xiao Long Bao 小籠包
