Five Guys is the way to go for burgers! They're massive and full of flavor. Don't get me wrong, In-N-Out is delicious too, but Five Guys just blows them out of the water.
I dont want to pay $30 for a burger and fries for one, so I prefer In-N-Out. I do miss the days of Five Guys being more affordable, but their lack of sales is their own fault.
5 Guys is so expensive now its crazy. The one in my home town even shut down. I went to another recently and it was like $15 for a burger and drink plus they wanted a tip.
