Yes, they make their own Ice Cream, and yes, they import their milk from corn fed cows in Illinois!
From their site:
Our ice cream is considered a premium ice cream based on the ingredient makeup of our base. We sampled milk from several different states and ended up choosing milk from Illinois cows! Our vanilla is a special blend of Madagascar beans. We process all our ice creams here in the store to give you the freshest product.
