We tried the regional burger chain many people say is the best in America to see if it lives up to the hype

In-N-Out remains a mystery to me, and the wonders of Chick-fil-A have only recently entered my life, thanks to its aggressive national expansion.

Whataburger had long similarly been an enigma to me - nearly every Texan I meet extols its many virtues, yet I had never set foot in one.

With more than 790 locations across 10 states, Whataburger is a Southern fast-food powerhouse.

It has been family-owned since opening its first humble burger stand in Corpus Christi, Texas, in 1950.

The chains ranks seventh on QSR Magazine's Top 50 Burger roundup, raking in $1.8 billion in system-wide sales in 2014, and it's expanding rapidly.

So when I found myself heading down to the Lone Star State, I decided a visit to the celebrated burger joint was a mandatory stop on my itinerary.
