Open prairie and highway traffic shape Waller, so good food needs to fit into a busy day. Carl's BBQ handles the basics with a calm counter and a quick turn. Use brisket as the clean test on the tray. It is the kind of stop that works between farm runs and school pickup.
Dickey's Barbecue Pit is there when you need a familiar barbecue restaurant routine and a predictable order. Add smoked sausage if you want a second bite with more snap, then get back to the drive.
