All this talk about fine dining experiences and no one has yet mentioned White Castle? It's 6:40am and I could eat a half dozen or so right now. Too bad there aren't any near where I live.
I am ashamed to say that I've never had a White Castle burger at one of their restaurants, but I did discover that they are available frozen in supermarkets. In my area (The People's Republic of Washington) they are carried at Safeway, QFC, and Sam's Club. They may be carried at other markets as well. They are probably not as good as fresh ones right from a White Castle restaurant but they are quite good, at least as judged by this stoat :-) Two of them cook from frozen in only a minute in the microwave.
