We were going to take frozen meat with us last year but didn't. Had no problem with customs but am not sure if your friend would have a problem or not. If you took meat in your luggage, frozen with those "ice" packs, I don't think you would have a problem, but again, locals to the board may have more information. We were glad that we didn't take anything more than snack food, because as you mentioned, the food in AC is so reasonable you don't need to bring much. Have a great time!
