There arent much food options in this station.
Just walk out of the station towards the market area. On the right hand side, you will notice many Maharashtrian hotels which are pure veg. A little walk further(150 mts from main stn building), you can find South Indian hotels. Food was very hot and tasty.
ATM's are avbl in this area. If you are changing trains @ RU, have great food at these places.
