No Andhra meals in Andhra

I drove to Gandikota and back. On the return journey, I kept searching for a hotel or restaurant labeled "Andhra Meals," but couldn’t find any! Why aren’t there any places explicitly labeled "Andhra Meals" in Andhra Pradesh like there are in Bangalore? If I want to find meals similar to those labeled as "Andhra Meals" in Bangalore while in AP, how should I go about it?
