This review concerns the White Castle hamburgers, commonly called "sliders". It is not about the service at the restaurants or the coffee, just the hamburgers... okay, the cheeseburgers too. Anyway, those little burgers are great. I usually buy them frozen at the grocery in a box of a dozen. I cook them in the microwave for one minute at 50% power. There, now you know how to do it. I'll eat one as a snack, two as half of a dinner, possible accompanied by chili. They have jalapeƱo cheeseburgers too, if you can find them. They too are marvelous.
