Where can you shop for cheap but quality groceries around Cebu City??

A friend of mine who was based in Cebu City told me that Colonnade Supermarket is the best place to shop for both dry and perishable groceries. She once described it as being similar to Mustafa Centre in Singapore due to the variety of goods stocked in the supermarket. Price wise, it's great for people who buy things in bulk, you pay less when you buy more.
