I remember going to one of the Horn & Hardart's automats when I was a youngster and was totally amazed to see food inside little windows on the wall. I have been looking for their recipe for lemon meringue pie but haven't been able to find it. I have the book The Automat which has recipes and stories about Horn & Hardart in it but, apparently, the authors weren't able to find this particular recipe. Does anybody have it? Thanks!
