The second concern I get is 'Food'. Agreed that when in Andhra, I expect much of meals and veg hotels but this is not even that.. Not much of option on main road, few small hotels. You have a very Lil/pathetically maintained IRCTC canteen right in front of the Railway station. To clear some doubts,  both Railway and Bus station are almost opposite to each other on road, small city in short. The bus stop host a clean pay and use Dormitory in case you need to quick freshen up.
