why do they still use styrofoam for to-go orders. It's terrible for our health. My food tasted horrible and a chemical-ish taste that was not there in the shepherd pie when I ate at the restaurant. Saving a few cents at the cost of the customer's health is terrible. EPA has already found very strong links to cancer, and most restaurants do not use it. I only found out after tasting the chemicals and freaking out.
