Fabulous traditional market. I wrote about this at http://travel.nationalgeographic.com/travel/city-guides/buenos-aires-traveler/
they do at both cotos near my old house (mexico 2200 & alsina 1900) and at the coto near my new house (liberatador 6800) plus @ the jumbo on acoyte last time I went. Also the disco on entre rios & belgrano usually had paleta de cordero which is just boneless leg of lamb basically.No? Unless I am missing something?
