“When Harmon Dobson opened the first Whataburger in 1950, his vision was to create a burger so good customers couldn’t help but exclaim, ‘What a burger!’” said Whataburger Group Director of Corporate Communications Pam Cox. “Today would have marked Harmon’s 100th birthday and we’re celebrating by offering the original Whataburger for just $1.00 plus tax as a thank you to our customers for making Harmon’s vision a reality.”

Family-owned Whataburger has proudly served its famous burgers since 1950 and continues to deliver fresh, made-to-order meals every day with extraordinary customer service. Headquartered in San Antonio, Whataburger has successfully expanded from a single burger stand in Corpus Christi to a thriving family of more than 750 restaurants across 10 states today.

In addition to the original Whataburger, the 24-hour restaurant is well known as a popular destination for late night dining and breakfast.
