It has been a long favorite not because of the cha Siow but the Yun Cheong sausage is my favourite. Lunch time only and hard to find a parking. Go before or after lunch time.
The cha siow is a little over roasted may not good for health but I guess one in a while is OK. Just personal view. As for their chili source also has a good balance with the cha siow and sausage. Overall is good. Buy per person portion with rice is much better price.
