I used to do field service, and one of the perks was to visit restaurants you'd never find if you stayed in Dallas area. Grannys is in what may be an old Dairy Queen location. Very no frills, but some of the best chicken you'll ever eat. A local institution in Seagoville and a pleasnt surprise to travellers. I wish a could buy chicken half as good at twice the price in Dallas. If you have to travel that way, plan on stopping in. Dine in or Carry out.
