About LA2HK's question about Shanghainese dimsums. You must be talking about the Xialongbao, pronounced Shalongbao.
Fantastic when well-made, like it is on the bylanes of Shanghai ( if anyone's really interested, try a small lane called Xapu Lu in Shanghai - check the map - for brilliant Xialongbao restaurants. One dozen steaming hot dimsums for 5 RMB !)
Many HK joints sell Xialongbao but most are quite disappointing. I'm told the Victoria City in Sun Hung Kai Centre in Wanchai serves pretty good ones. I'm sure Victoria City in Citic Tower in Admiralty serves it too.
By the way eating Xialongbao can be a bit messy if you're not careful. There's hot soup inside the dimsum ( a gelatinous mixture of pig skin and feet among other things) which 'projectiles' out at the first prick of the chopstick.
