Prime rib at Killen's Barbecue

Yesterday, one of my best buddies had lunch at Killen's Barbecue (Pearland, TX). Prime rib, with creamed corn and macaroni & cheese. He texted me a pic:

Best BBQ in Pearland?

Pearland is home to several BBQ joints. Admittedly, I've never been to Pearland. I have a feeling about what people will say, but...what's the best BBQ joint in Pearland?
