Barbecue is messy eatin’. The fewer people to see you go ballistic on ribs, the better. Even though Houston is a drive-thru town, most of us aren’t aware the ubiquitous Pappas restaurants offer window service. Try the daily special choice of three meats and two sides for $8.99, and you’ll get the sauce and bread alongside, but if you ask nicely, they’ll also be happy to pass you pickles, onions, jalapeños and anything else from the condiment bar. You get all the benefits of visiting a barbecue joint without the unseemly public scarfing.
