The best time to visit Khazana is not for lunch, when the buffet at this off-the-eaten-path Lone Tree Indian restaurant looks all too familiar. But if you come for dinner, you'll find delicate, bronze-tinged dosas paved with a beguiling mix of curried potatoes and onions; Indo-Chinese dishes like cauliflower slicked with infernal chiles; intensely spiced curries served in shiny, V-shaped copper vessels; and Indian street-style chicken with scrambled eggs, tomatoes and boom-boom spices — tastes that manage to be both refined and bracing. The animated menu phrases that accompany the dishes — "Are you crazy??? Every Table's got to have one," exclaims the ode to the chicken-wing lollipops — might seem like overkill, except that every single dish here is absolutely killer.
