There is a stall in Food Republic on level 4 of Wisma that seems to do double-boiled soups that are above the usual food court standard.
For instance, my order of the (inaccurately-named) "Pig Tripe Soup" was cloudy with a strong peppery kick and had plentiful slices of pig stomach and pork rib, plus a couple of ginkgo nuts and "gao kee" herb. I enjoyed this nourishing, belly-warming bowl more than I expected, to be honest.
