I have to laugh here at SMD's comments. My breakfast this morning at my house in West Anaheim, I microwaved White Castle Cheeseburgers. And yes, when I am in an area that has White Castle restaurants, I want to stop and grab some sliders, which are much better than the Frozen version.
Along the same thoughts, Krispy Kreme Donuts (one is nearby at the Outlets of Orange. there is a big difference between picking up a box at a grocery Store, and actually going to the restaurant, where they have a "show kitchen" so you can see the classic donuts being made, and the "Hot Doughnuts Now" neon sign. The Original Glazed is the classic, but simple and basic, just done well, and tastes better when you can eat them right out of the fryer.
So stop in at a In-n-Out Burger, and take advantage of the free hats and bumper stickers they hand out. (And there is a classic story about how one of the first versions had to stop being made, due to some people being creative and removing a couple of letters....)
