In N Out burger is great but there's always a huge line anytime you want to eat. Their fries, burgers and shakes are awesome. Nowadays A's burgers and Smashburgers are bigger here in SoCal. A's burgers are just as good and give you twice as much meat for the same price, and when you order fries or onion rings you get a huge serving.
In N Out failed in giving too small of portions and huge waiting time for their product, it might be great for the owners ego seeing lines of people all day everyday, but failing to open up enough locations and server customers fresh food quickly is leading them to lose market share to A's Burgers and Smashburger.
A's Burgers and SmashBurger serve quick fresh food with huge portions taking In N Out burgers market share here in SoCal.
