have to chime in on Sonny's. i work w/ my dad, so we eat lunch together often. he grew up with Sonny's kids, and he has good old day's syndrome, and is blinded by the fact that sonny's sucks. i have to go the the location on lovers about once every 2 weeks. gotten to the point that all i get is either a baked potato (no meat) or a chicken salad.
sonny's isn't worth a damn. the best bbq i've found (other than 1st & 10's ribs) is lockhart in bishop arts. other than that you have to get WAY out of dallas.
