I have heard of Shake Shack, but I don't know a thing about it. I keep picturing it as equivalent to Steak & Shake, in which case I don't know why this would be news. Steak n Shake, with cleaner, cooler-looking restaurants and better service, with worse food, on a coast. Steak n Shake food isn't all that great, IMO...so this doesn't fill me with excitement.
