I am sure most Singaporeans will be familiar with the Yaowarat district in Bangkok. It is popularly known as the Chinatown of Bangkok and it is where you go for Thai-Chinese food. I haven't really explored the food at Yaowarat much even when I was living in Bangkok in the early 2000's. The place is a traffic nightmare and I remembered it for its numerous shark's fins restaurants!
I think the challenge for anyone entering the zi char business is to be able to come up with one or two signature dishes with the ability to capture people’s attention. You Huak managed to do it with their seafood white bee hoon, New Ubin with their beef fried rice and Royal J with their fried porridge. Just being competent in the usual compendium of zi char dishes will only get you so far.
