well, I think you went to the wrong stall in Singapore. heheh....
some are oily but it taste good, I think an occasional indulgence if fine. :-)
anyway, I do think both HK and Singapore has a good variety from different parts of the world but for the dimsum I missed most, it has to be from my trip to Guangzhou, China.
So much action in this post I have decided to follow @mibenkito and @englishchrivy and if you folks are in Singapore, let me buy you our local coffee.:-)
