Every once in a while, someone comes up to me and conspiratorially recommends what must by now be the worst-kept secret in South Delhi’s “offbeat” food scene — Khan Chacha’s kabab corner in Khan Market. Frankly, I find said place more than a tad over-rated — the kabab rolls tend to be all shmushed up inside, and you can barely discern anything more than a floury-meaty taste.
