PRO: A good simple menu and friendly staff which applies to all locations. Don't go on a Sunday or Saturday, especially at night--the line will be a mile long and can take an hour.
CON: TRUE story--you can't make this stuff up. I ordered two burgers, started eating and felt a "string" like thing in my mouth. Figured it was fat in the meat. Started eating the other one with cheese and same thing. So I took the burgers apart and I couldn't believe what i was seeing--red hair everywhere. Not on the meat but COOKED IN THE MEAT! This doesn't happen by accident folks. I showed this mess to the manager and made sure he saw it was cooked IN the meat so there was no way I put it there. I also pointed out it was red hair and I had only seen one person in the back with red hair so it was obvious who the guilty party was.
All he would do is give me a coupon for two free burgers. I really wanted to have the little red headed bastard come out and explain what his issue was but I just left. Hope they fired his ass. It took me 4 months to get the urge to go back to In & Out. So for that I am removing a star. But four stars is still good and the food is good too.
