I had a different experience on the 29th at BPQ (Balharshah) - was pretty hungry when the train pulled in to PF1.. Was greeted by piping hot Vada sambar for Rs 30(4 Pieces) - very tasty. You can also pick up veg meals or Veg/Egg Biryani.. Veg Biryani costs Rs 50/-. Washed it down with a piping hot tea.
