If you are looking for something plain and yet it can fill up your stomach, a good food to try will be kway teow th’ng which comes with clear soup based, sliced meat, fishballs and meatballs. It serves with white flat rice noodles. Also, they put a lot of the chopped garlic. You can find stall selling this noodle in almost every kopitiam shop in Penang. It is very common. Even they put a lot of the fried garlic, the soup is not too oily.
I quite like this noodle, simple and filling. I even tried to cook this at home at times.
This kway teow th’ng noodle shop is located at Jalan Burma, I could not remember its shop name, however, it is located opposite of Kedai Kopi Swee Kong. You will be able to see this shop at the T-junction.
