I am a fan of Luke's from my youth in Tucson, where they provided a nearby source of yummu chicago dogs and bigger-than-average burgers. Let's be honest, the burgers are decent but unremarkable. They are, at least, consistent in their mediocrity. Luke's can't hold a candle to Delux or the Sonora Brewery, but they are definitely cheaper, likely closer and they've a down-home feel.
The customer service was fantastic and incredibly friendly. I definitely felt very welcome and the atmosphere was warm, even if they muttered about my Red Sox stomping the White Sox on the t.v. and changed it because they couldn't bear to watch.
hah!
