Is buying a first class ticket from Jaipur to Mumbai worth it?

It's a short flight, and I'll be just fine in economy. But I'm an airline geek, and while I've flown both Jet Airways and Kingfisher in the past, I've never flown their premium cabins, so I don't know what kind of service indian airlines provide in F.

I couldn't find any useful information on Jet Airway's web site regarding their service on this flight. All I understand is that there is supposedly a lounge in JAI.

How are the seats, how's the service? I was favorably impressed last time by the food in Y, is the food in F a step above? In other words, would you buy F just for the experience or is it a complete waste of money?
