Normally, I’d be suspicious of a restaurant that attempted to serve foods from pretty much every region of the vast country of India. But somehow Chola makes it work, whether sending out perfectly crisp yet supple dosas (a form of Southern Indian pancake, often wrapped around other ingredients); chicken tikka masala that’s both moist and flavorful; and the Calcutta dish of lamb and okra cooked in a sweet and sour sauce (another knockout). The lunch buffet is especially recommended; beyond the buffet table, waiters walk around with a number of freshly cooked specialties, at no extra charge.
