Breakfast at Visakhapatnam(arrives 30-40 min late generally)I suggest steaming idly because remaing food items can be preserved an can be the previous day's preparation.Idy is perishable item so they can't serve previous night's Idly and take only hot Sambar if not adjust with Pickle or Curry leaf powder which are available on platform.Never take Yellow rice(tiger rice) for breakfast because there's a probability that it's previous night's rice.
For lunch there is'nt much difficulty. You can have it in BZA(Vijayawada).There are plenty of options.If you want to get down at BZA and board another train you can have lunch at comosum in buffer time.Try tasty Onion Samosa after lunch if you wish.
Before...
more... dinner time you will be in Secunderabad Sir.
This is what I do in my travelling. Thank you SirЁЯЩП
