We like to track how certain restaurant chains are or are not in certain states. For many years, one of my favorites in California — and only a few other states — was Koo Koo Roo. Alas, the last Koo Koo Roo has closed and it looks to be gone for good…but one of its old locations in West Hollywood is soon to become the first Shake Shack in my state. Many people are excited. If I'd ever dined at a Shake Shack, I might be, too.
