I just went to Bayu Tinggi branch, and tried out the Siew Mai, Har Mai and Char Siew Pau (take away) at about 12.12noon, Nov 02, 2023. It is quite disappointed that the Siew Mai is not fresh, 3 pieces of the siew mai tasted not fresh and a bit sourness. Har Mai is fresh and good and char siew pau is juicy and not too sweet. As what you mentioned here, they have improved and changed, but seem like it is not totally improved in all aspect. I have yet tried others, but I think i will not try for now.
