Whataburger is experimenting with food delivery in certain parts of Dallas this week.
The Texas-based fast food joint started trial runs on Monday using third-party delivery company Door Dash, which allows users to order food from restaurants via a smartphone app.
Door Dash told FOX4 this is not an official partnership with Whataburger and it may end the test any time as the data comes in.
Door Dash is already familiar with North Texas, having recently contracted with Dallas-area Taco Bell locations for delivery service.
