Airport : CCU (Extreme left side of the terminal building)
Lounge : Travel Food Services (TFS)
Access : Diners Club, Amex Plat Cards, Master Card
They advertise themselves as all of you can eat for 999 place. The buffet spread is decent. The airport is huge after the recent renovation, in comparison the lounge feels miniscule.
Sorry for the bad pic quality, I am not very comfortable in taking pics of public places
