I am looking for a butcher or gourmet shop that carries sweetbreads in either Center city, U-city, Old City, or italian market areas. I have been looking around but have had no luck yet. Thanks for the help!
Try the Fair Food Farmstand in the Reading Terminal Market. If it's not already in the freezers you can special order it. I don't know about you, but particularly if I'm going to eat animal offal, I'd want it from one that was well reared.
