I first learned about this roast stall called New Rong Liang Ge Cantonese Roast Duck Double Boiled Soup from the TV program "Where The Queue Starts" (排排站查查看) several years ago.
I have bookmarked the stall since then but have never gotten round to trying it. When I visited the newly reopened Old Bukit Purmei Lor Mee recently, I realized this roast stall is located right at the next coffee shop along the same row under Blk 269B Queen Street.
Fast forward one week later, I am back to check them out.
