Transfixing all of Delhi with an exceedingly singular concept of booze exchanges, these awesome cafes and pubs have come up with an ingenious plan to get you drunk - on the cheap! How it works is - they list all their booze (or most of it anyway) on their own special exchanges, and the price of your favorite pint of beer would then plummet or rise, all as per demand forces naturally and voila! You stand to make a killing buying your drinks at throwaway prices. Ah, the modern age has such marvels to offer *wink wink*!
