Personally I would blow them both off as I am a fan of REAL food! Face it, all they serve is what really comes out of the BACK of the cow, wrapped in a bun or over-bloated wrap! REAL food is what we HUMANS should actually be eating, not this grease laden, overcooked rubbish both chains laughingly call food!
I know how to cook REAL food myself so I would not waste my time or lower my high standards by entering their disgusting establishments! If you want to keep your health people, you would also do the same!
