Whataburger posts a lot on Twitter, often times several times a day. Their posts are sometimes pictures of their food, but other times they are about things going on in the the states where they have stores. Recently they have been posting a lot about South by South West, which is taking place in Texas this week.
They also have a website https://shop.whataburger.com/Products#!/gift-cards?gclid=CNWnuuPwjr0CFUVp7AodW3YAtg where they sell merchandise and their delicious ketchup and mustard. The website also has a section that highlights good events and happenings in communities.
They also have a Facebook page https://www.facebook.com/whataburger where they post a lot of the same things that they do on Twitter. Their newest post is of Conan O’Brien at a store in Cleburne, Tx.
All of Whataburger’s pages have the logo as the profile picture and a picture of their food as the banner. Although it isn’t the same picture of the food throughout their profiles there is a since of continuity.
