by far the best schnitzel i ever had was in vienna austria. the veal there must be different, because i've never had a schnitzel as good.
the worst was in a country inn not too far from kitchener on. they are known for their great pork hocks, but i chose the wiener schnitzel because i wasn't that hungry. on the menu it was advertised that the schnitzel was veal. oh. that's nice. what i got was a preformed patty which came in frozen(i know these things) and deep fried. what a disappointment. a fresh pork or chicken schnitzel would have been so much better.
the 'classic' way to make a schnitzel is to not deep fry it. it is pan fried in butter and veggie oil. most places, even european places tend to deep fry.
