DELHI, at last, is taking its food seriously. Till recently, the Punjabi palate was quite at peace with the ubiquitous Tandoori chicken. And though we havent heard the last squawk yet, the capital seems to have suddenly developed a voracious appetite for an experience thats decidedly differentthe global gourmet taste. Consider this: in the last six months, of the eight new eating places that have opened, only Qutab Mulakat serves the standard Delhi fare. The rest are all refreshingly different.
