"McDonalds serves all-beef in their restaurants, I don`t think there is
any pork served. Halal may be the problem, however. Jews have the
same problem of they are observant."

Strictly observant Jews can't have McDonald's hamburgers for two
reasons: (1) they cook pork and dairy products on the same grills as
beef, and (2) the cows that the beef comes from are not slaughtered by
the kosher procedure.
