Rehan and Nishant got jobs in IT sector and were based in Bangalore. Rehan was from Delhi and Nishant was from Gujarat. Both were missing home food. The canteen food was highly unappetising. They checked out several tiffin services but did not find them satisfactory. The food was not apt for their taste buds. So, they decided to quit their jobs and start a professionally managed tiffin service by the name of 'Sanjha Chulha' They not only gave chapatis and North Indian curries, but also started with 'Gujarati thali', 'Bengali thali' as regional meals. What was the source of perceiving the basic idea?
