It's always a toss up between In-n-Out and Five Guys when my boyfriend and I are trying to choose where we want to grab a burger.
I usually get a little cheeseburger (little = single patty at Five Guys) and add mayo, grilled mushrooms, raw onion, tomatoes, pickles and lettuce. But the best thing about their burgers is you can easily choose from their list of items the things you like. I have never had my order come out wrong.
The other awesome thing about FG is the regular size fry is more than enough for two people to share. I also love their new soda fountain dispenser-- it has a touchscreen LCD display, and you can choose from many different combinations of Coca Cola like diet Coke with cherry or Coke with orange-- pretty fancy if you ask me! :)
I am also a big fan of the employees and managers here. They are always friendly and helpful, and always come around to the tables to make sure everyone's food is alright.
