Kanye West -- I'm Lovin' It ... Lambo With a Side Of Fries

Kanye West isn't the new Hamburglar, but he should be ... he rolled through a McDonald's Thursday in his slick black Lambo Aventador ... proving even icons need a fry fix.

Yeezy must have been suffering a DEFCON 1 Mac attack, since keeping a low profile was obviously not a priority. Hey, sometimes the golden arches call out to ya ... even if the aroma clashes with the fancy leather scent in your $500k whip.

Question is ... did he save any fries for Kim? The man's only human -- of course he didn't.
