This is my new favorite food stall in JEM. For $3.90, you get a "diet size" Serawak Kolo Mee that is tasty and full of pork meat. I find the size is a bit small though, so I will buy two portion of it for $6 (promotion price).
The kolo mee have 4 taste: white, black, spicy, or black and spicy. My wife tried the black and spicy kolo mee but she found it more like ordinary wanton noodle. So I would recommend white (traditional) kolo mee if you have the chance to visit this stall.
They also have various pan mee menu but I haven't tried it.
