Largely known for their "char siew", which is the sexy dark-coloured type, Foong Kee on Keong Saik Road also does a "sio bak" just the way I like it - salty and with a crackling of resoundingly loud crunch.
Their wantons get the thumbs-up from me as well because the filling in them has that traditional taste which is getting increasingly hard to find these days.
