According to the Map and my personal experience there are three food outlets: available: Foodies Bar, Mumbai Se, Shivsagar and Snack Bar. But all four are OUTSIDE the terminal but very close. It is still convenient, but you are in a place where not just passengers but others have access to and therefore crowded. SAfety issues with luggage will also need to be looked at carefully. I personally dont like to be outside the arrivals lounge in any airport in the world because of the presence of taxi drivers, hotel touts and general public whose antecedents one does not know. But then it is a choice which a passenger has to take himself. And I would not reccomend it. The interactive map of the arrival terminal is available at the website www dot csia dot in
