After a reading reviews from this site I thought I'd give this place a go and love it so much I've been back 4 times since. I've introduced 2 people new to dim sum to it at this place and they were instant converts.
I've sampled most of the dim sum places in Chinatown and this is the one I return to the most. I love checking the dishes out on the trolleys before deciding what I fancy that day. The lack of prices is a bit bugging though as I've stitched myself up with bigger than expected bills when I've been hungry (or was it greedy?).
Chuen Cheng Ku serves a wide range of inexpensive Cantonese dishes. It is advisable to make a reservation. They have a take away service and can cater for private parties of up to 180 people upon request.
