YOU SAID:
Food is my best friend besides me
INTO JAPANESE
私のほかに食べ物が私の親友
BACK INTO ENGLISH
Food besides me is my best friend
INTO JAPANESE
私以外の食べ物は私の親友です
BACK INTO ENGLISH
Food except me is my best friend
INTO JAPANESE
私以外の食べ物は私の親友
BACK INTO ENGLISH
Food except me is my best friend
That didn't even make that much sense in English.
