There's a place I know in the hood that is a meat wholesaler that sells to restaurant at rediculous prices. It's in NW miami about two blocks N. of NW 20th st. around 14 ave. I used to buy there when I lived in Hialeah, filled up my freezer with $60.
I don't have a name or number for you but if you google I'm sure you'll find it. Oh, better bring someone that speaks spanish.
