I was at a spanish themed cocktail party friday and someone brought along 20-30 of the best empanadas I have had in Boston. Significantly better then the place in Allston and those ain't bad. I had both chicken and beef and both were packed with filling, juicy, and delicious.
I am told they came from a place called Chachos that is really mostly a pizza place:
