Time Out says
What merits the stall's popularity and volume of customers is their stir-fry technique using charcoal flames as opposed to frying them over a gas stove. Perched at the end of Jalan Siam, this char koay teow stall has been a favourite among Penangites since its opening many decades back. As the owner operates only with one assistant, prepare to wait with other local regulars for your order (many have said to wait for 20 minutes or more). However, it's well worth the wait since every plate is stir-fried to perfection with fresh ingredients. There are no seats around the stall, so enjoy your plate of char koay teow at the Chinese coffee shop across the street.
