I know that most of the questions posted here are about restauarants, but I thought that maybe someone might be able to help me find a place to buy frozen tilapia loins around the chicagoland area. I used to find them at COSTCO but they stopped carrying them and I have searched and searched but I cannot find anything but fillets. I really like the loins so much better. I even tried the supplier of the COSTCO brand and they could not help me. Any suggestions?
