The Pantry Car is just a empty compartment that is dragged along the whole journey. It should be marked as Pantry Not Available.
Catering was available for the evening dinner and the next morning breakfast. But after that, there was nothing available leading to a mad rush at (a late running) Mangalore for lunch. Facilities at Mangalore was not good at all - only options available were Fish Curry and Veg Biriyani.
