Since 1950, Whataburger has proudly served a bigger, better burger. It all started when a young entrepreneur named Harmon Dobson had a bold idea: to serve a burger so big that it took two hands to hold, and so good that after a single bite customers couldn't help but exclaim, “What a burger!” He named his humble burger stand in Corpus Christi, Texas, “Whataburger.” Over six decades later, we're still family owned and operated. Each and every Whataburger® is still made to order. We still use 100% pure beef and serve it on a big, toasted five-inch bun. And now, as we proudly serve burgers, chicken, salads and breakfast at more than 800 Whataburger locations across the country, that first burger stand is still close to our hearts.

- JRJeremiah Rodriguez4 days ago1.0Slow service . 20 minutes in the drive through for one small simple entree.
- AAAriana6 days ago5.0My other go to after dance class and socials!! 12:30-1 am snacks to get me through my sleep until morning! I danced off those calories and have to put them back in!! A 24/7 WB needs more workers! We are waiting too long to get a plain a dry cheese burger at 1 am!!!
- KSKevin StolteOct 2, 20261.0I’m not usually one to leave a bad review, but you people really earned this one. The service was great, but I’d like to personally thank you for $40 worth of inedible breakfast. I can hammer nails with these biscuits, the buns aren’t much fresher. Maybe I’m spoiled by spending the last 2 years by a Whataburger that actually cared about the food they put out. This is absolutely pathetic. Shameful. Never goin back to this one, I recommend yall do the same.
- AGAiden GraysonOct 2, 20261.0Good food but man fries are always soggy at this place
- DDDustin DSep 6, 20261.0Stopped on a road trip to get a quick breakfast. Restrooms were unavailable due to being cleaned (I get it, no big deal). Ordered 4 sandwiches and then waited longer than we've ever waited at any Whataburger for our order. The lady in front of us got tired of waiting for her taquitos and got her money back. Finally was handed my bag and we left since we had wasted 20 minutes of our time. Down the road, realized they only put 3 sandwiches in the bag. Apparently they can't count to 4. Worst Whataburger I've ever been to. Other locations do a great job...this location needs to do better.
