You are kidding me right? I like Whataburgers but it doesnt even compare to IN N Out.
I can WALK in at lunch time at any WB joint anytime. TRY doing that at In N Out in L.A...ANY Socal joint and you will be standing and parked in your car for hours.
When I lived in SoCal (many years ago) there was a Whataburger in a then rural part of Orange County—with no waiting time ever.
But—I am sure those days are over...still miss the burgers—haven’t had anything close since I moved back to the Northeast.
What makes me laugh when someone compares In N Out to any of these other burgers. They are half the cost of the other chains.
