USJ21's 鴻豐 Hoong Foong Dim Sum (have been here since 1999, more than 20 years now), is no slouch; perhaps still have its own regular customers (fan base).
Dim Sum prices are still at rm$5 - rm$12 per plate, with average prices around rm$6/plate, generally considered reasonable and affordable.
Both 上汤竹笙券 Bambo Fungi roll & 上湯蝦球 Supreme soup Prawn ball sampled today are definitely worth ordering!
