Faasos is a fast-food chain (called QSR - Quick Service Restaurant) in the industry jargon, based in Pune and Mumbai (as of now - it is expanding to other Indian cities).
They have decent food at fairly reasonable rates (given the inflation in India from the last few years, that is).
Among other things, they use Twitter to communicate with their customers.
I order food from Faasos now and then.
