Im very picky with my burger condiments... I dont like Mayo/thousand island based sauces and not a big fan of mustard+ketchup on my burger. BBQ sauce and A1 are usually the only ones I'll use on a burger but most places use nasty cheap bbq sauce and dont offer A1. So at many places I'll have my burger "plain" with no sauce which I believe has given me a ton of experience of what places are serving legit burgers that dont taste dry and flavorless without sauce smeared on it... And In N Out is king at that regards. Their patties are made so juicy and flavorful you can easily eat it without their spread.
I dont like their fries but the burgers are so good and at such a good price I dont mark down my rating for that. Also their shakes are some of the most affordable I've seen.
And lol at all the haters from the east coast who obviously had their mind made up that In N Out cannot possibly be better than their local favorites before trying them. As a burger fan Ive tried countless places including favorites from other regions without like shake-shack and Five Guys that I enjoy and visit too. Is In N Out my absolute favorite burger? No but its one I keep coming back to the most for their convenience and unparalleled bang for buck ratio.
