The southern suburbs, with their mega-priced steakhouses, chain horrors and multimillion-dollar mansions, are hardly where you'd expect to find the most interesting Indian restaurant in the city — hustling Indian street food, no less. The two Mirch Indian Grill outposts are brightly hued, comfortably informal shrines to Bollywood, where Indian pop music pulsates from the speakers while the kitchen turns out authentic foods that have made that country a culinary mecca. The menu, which reads like a personal travelogue, is full of beautifully prepared, flavor-bombed dishes, including "Frankies," griddled rotis smeared with chutney and a thin layer of scrambled egg and rolled with cubed lamb, chicken or potatoes; somosa chaat spread with yogurt, chutneys and chickpeas; meaty kabobs; and aloo tikki, crisp potato patties lashed with bold spices. Just make sure to save stomach space for the diabolically good mango ice-cream sandwiches.
