When the Nashville hot chicken trend rolled into Dallas several years ago, we scoffed. Tennessee is the Volunteer State, not the Muy Caliente State, and this is Texas, the eternal home of pepper bellies. So we headed off to one of the new "hot" joints and ordered the hottest they had, looking smug. After we woke up and could see again, we understood: What those Tennessee folks are volunteering for are medical experiments involving pain tolerance. So, they know hot, and they damn sure know how to fry up a chicken. Hattie B's nails it with a crunchy crust that doesn't overwhelm the bird with breading. It's moist but not greasy, the non-lethal spices bring out the flavor of the meat and the pieces are plump. They offer bone-in and tenders along with a chicken sandwich and Southern-style sides including greens, baked beans and black-eyed pea salad. We can't tell you about the hottest of their six heat levels ... because we're cowards. Apparently it's a religious experience, as we've seen people at other tables jump up and say the Lord's name.
