The braised duck rice from Heng Gi Goose And Duck Rice at Tekka Market & Food Centre was added to my checklist years ago however, I have not gotten the opportunity to cross them out yet.
I do pass by Tekka via the downtown line occasionally but it is impractical to walk out of the station while in the midst of a journey just to try the duck rice there.
To my surprise, they opened a stall at the new Senja Hawker Centre which is so much more accessible to me now. I know I have run out of excuses putting off what I needed to do eons ago.
