This place has been around for as long as I can remember. It is a staple in the First Markham Place Food Court. It's right in the middle and probably one of the bigger stands in the food court. The whole food court is busy during lunch hour but I see a little line form in front of Yan's more so than other stands.
I always get their Shrimp Siu Mai which is 5 pieces for $3 flat no tax which you really cannot beat. They are big pieces too! 5 pieces is honestly enough for me on days where I'm not too hungry but still need to eat something so I'm not grumbling the rest of the day. You can fill your own sauce cup on the side.
