Moh Teng Pheow Nyonya Koay is one of the biggest kuih makers in Penang. They operate a canteen where the locals come to enjoy various types of Nyonya kuih. The canteen is open Tuesdays to Sundays from 10:30 am to 5:00 pm. Most people might not know it because it is located deep at the end of Mesjid Road off Chulia Street. Patrons to the canteen walk through the kitchen area to get a first-hand view of how the various kuihs are made.
