Must admit, I'm in the "I don't get it" camp. Was in L.A. last week and decided I'd give In 'n Out another try. I had tried them 3 times previously, and had always found everything lacking. Having continued to read about and hear all the hype, I decided to give it one more go, thinking perhaps I had missed something. Not only were all my previous experiences substantiated, but this was in many respects, my worst experience yet.
Had two cheeseburgers with onions, fries, and a chocolate shake. The burgers were overcooked, dry and tastless (I even tried pulling the patty out just so I could taste the meat. Did not taste any of the oft referred to "fresh ground beef tatse"). Yes, the lettuce and tomato were indeed fresh and tasty, but when it's masking a tasteless hunk of beef, so what? The fries were laughable. They were cold and tasted like cardboard. The shake was so sweet, I thought I might end up in a diabetic coma. The consistency and mouth feel... I would best describe as melted plastic. Needless to say, I didn't finish any of what I ordered.
I understand of course that your experiences may (and in many cases do ) vary significantly, however for this burger lover, it's my last time there.
