Consider south Indian fare to be the Provencal cooking of the subcontinent. There's an emphasis on tomatoes, ginger, rice, chili peppers and bold seasoning used to prepare vegetarian meals that satisfy without leaving you overstuffed. Udupi Bhavan, which is billed as a "pure vegetarian" Indian restaurant, specializes in southern Indian cuisine. Just remember that at this humble eatery, the food is truly the thing. Ignore the sparse décor and self-service trappings and enjoy a cuisine not often found around here.
