Fearlessly spiced with garlic, ginger, chile, onion, cumin and curry leaves, the food of south India is some of the best in the world. And Masalaa, a divey storefront surrounded by international markets in a dilapidated strip mall in Aurora, is the sole Indian restaurant in the metro area that really delivers the goods via uttapams, spongy idlis, savory vada and superb dosas — shatteringly thin crepes, tinged golden, that conceal hidden gifts of seduction. Masalaa hustles nearly a dozen different dosas on its menu, but the masala dosa, rolled around nothing more than a heap of curried mashed spuds powerfully scented with intoxicating spices and served with a trio of chutneys and sambar, should be on everyone's must-eat-now list.
