In-N-Out is a good honest burger for the price. It is not the best burger I've ever had, nothing close to restaurant that charges 50% more like The Counter locally, or even Five Guys.
Some say Habit is better but they charge like $6-8 instead and their lettuce is not as crisp and tomato not as fresh.
I enjoy In N Out and lunch there all the time, but it is a fast food burger still, not a gourmet burger place.
I'll take In-N-Out over Five Guys or Habbit.
Boutique burgers will always win the day, over chains. There is a "Burger City Grill" in my area, and it puts all those to shame. It's a good bit more expensive, though.
