In-N-Out Burger became a fast-food legend for its simple, yet just big enough menu. Of course, the burgers aren’t half-bad either. But what if a place were to take that simplicity, but kick things up a notch in ingredient quality? That’s where Little Big Burger in Portland comes in. Simple menu (6 items including drinks and no secret menu to speak of). Good prices ($3.75 for a cheeseburger). And hopefully delicious food.
