carne de res
It means beef (cow meat).
This seems to be the Latin American word for beef - in Spain it's called carne de vaca
I'd hate to eat beef in Chile because that makes me think of "vacuna" (shots) and I'd just picture my steak getting a needle stuck into it.
actually "carne" makes reference to the meat itself while "res" talks about the dead cow. So yeah, basically it means "beef"
