To be honest, I have not heard of this stall named Beijing Time-Honored Cuisine before even though it has been there at Chinatown Complex Market & Food Centre for a while.
I guess it is easy to be overlooked when the stall is sandwiched in between the bigger names like Hawker Chan and Heng Ji Chicken Rice. The situation is made worse when another stall with a similar menu is ]located directly across them. The stall in question is Zhong Guo La Mian Xiao Long Bao and it had a Michelin 2018 decal proudly displayed on its display window.
I only got to know about this stall when I came across a photo of their pig trotters rice on Instagram which prompted me to come check them out.
