San Xi Lou HK tips
Anything on the Sichuan side of the menu - they have Canto/Shanghainese (I think) as well - no go.
2 things i particularly liked:
shui zhu yu (fish cooked in trad Sichuanese (is that a word?) style in a pot of chilli + oil) - fish is tender and slippery.
zhang cha ya (lit. sauce + tea duck - a smoked duck of sorts). the meat is a little dry (think confit), has a great smoky flavour and falls off the bone - ideal for giving your tongue a rest from all the ma la.
the hot pot (chilli based, of course) looks quite good too and a lot of people seem to go there just for that, but i've never ordered it.
