The franchised food choices are decent.
They opened Reliant with Luthers, but no longer have them and the BBQ they have now is meh.
Papa Johns is okay.
Princes Hamburgers is an improvement over the old ones.
The best food options ever was at Compaq center before they moved to Toyota Center. They had mostly franchised food and it didn't taste worse than if you went to a restaurant. Various Pappas restaurants, Pizza Hut, Whataburger, etc.
