This is a Taiwanese version of Shanghai cuisine that makes one of the best tasting Xiao lung Bao (soup filed crab and pork dumplings), as well as many other dishes. Always a line to get in, but always well worth the wait for the amazing food to serve.
They have branches in different parts of the world, but if you've never eaten at one, you need to. It's that good! Foodies like myself go for their dumplings and soup noodles, because it's that good! Also, the location is very easy to get to being located in Causeway Bay and a short walk from the MTR station.
Try getting there in their non-peak hours to avoid the long lines.
