Every once in a while a Chicago snowbird opens a "Taste of Chicago" diner in my town. They never last. Since the cooking websites got going, I've resigned myself to finding ethnic recipes and doing it myself.
Its hard to make a go of restaurants....they come and they go, its often hard to be a success...the main place we went for our Chicago dogs and Italian beefs, was always jammed, sometimes hard to get a table...and they always had a big take out clientele as well....they were a great success...I so wish they had not closed, due to a family crisis...
but the cooking websites certainly do provide the recipes for those of us who miss regional foods from places we used to live in...we can cook it up ourselves...
I still miss the great hushpuppies, and bar-b-que we enjoyed in North Carolina, when we lived there...
Every region of the USA has it local specialties, and foods and ways or preparation unique to the area...
