On October 22nd, 1948, 73 years ago, the first In-N-Out Burger was opened in Baldwin Park, CA. The original store was barely 10×10, but started a long history of Quality You Can Taste. Proof that anything is possible with hard work and an unwavering commitment to your goals. Today, you can visit the Replica of the Original In-N-Out Burger with tours running Thursday-Sunday from 11am-2pm. Can anyone tell me how many burgers we sold on that first day?
