Is it possible to order a milkshake with a breakfast menu?

Some stores may have Milkshakes available during breakfast, but it really depends on the store. All you have to do is ask at the counter. The reason it isn't standard practice across all restaurants is because some stores use the breakfast shift to clean the milkshake machine. But don't worry, if you can get a Milkshake with your breakfast, we can guarantee the machine will still be sparkling clean.
