One of my go to places, notched in my favourites list.
Mei Sek seems the busiest kopitiam among the 3 both in the morning for the hawker food as well as night time for the Bean Sprout Chicken Rice.
My breakfast was 三间庄猪肉老鼠粉 Porkball dry Loh Su Fun, a bit oily but that's typical of a good bowl of dry porkball noodles.
I am trying the Chasiew Wan Ton Mee today. The stall name is 兴记 Heng Kee, the chef and only person managing the stall is a foreigner and likely Myanmar.
