I live in the Midwest and have been told this is the main reason this will most likely remain a West Coast chain. I've also been told it's a case of freshness. If they have to ship all the ingredients from California to Iowa, it's not as fresh as they want it to be. Keeping the supply chain close and using local suppliers for specific ingredients allows them to have a consistent product no matter where you get it. At the end of the day, as an owner, that's what you want. No matter where the customer goes, they always get same fresh, great tasting product.
