Portillo’s Style Italian Beef and Cheddar Croissants

 Portillo's Style Italian Beef and Cheddar Croissants 7

Since it was Father’s Day over the weekend, Cliff’s first, we decided to let him pick whatever he wanted to post on the blog. I shouldn’t have been surprised when he picked beef and cheddar croissants. It is kind of like his thing. If you look at our instagram account its pretty much, beef and cheddar, baby, baby, baby, baby, dog, beef and cheddar, beef and cheddar, beef and cheddar, Lou Malnatis. I guess when you find something you like you stick with it.


Cliff’s most favorite thing to get at Portillo’s is a beef and cheddar croissant with sweet and hot peppers, cheese fries, and a beer. I have his order down pat. Personally, I prefer a hot dog plain, (I know, very unchicago of me) fries, and either a chocolate shake or a piece of chocolate cake. If I’m feeling really crazy I’ll order a chocolate cake shake.  I am a wild one!  For those of you who do not have Portillo’s near you ( I am so sorry) this is your chance to make the next best thing!
