The first of which is Udipi and the other is Madras Woodlands which is just up the road on the same University Drive.  If you've never experienced south indian food, you are in for a treat.  The south indian diet is maily rice based, so you'll see that a lot of the menu has rice as the main ingredient.   I recommend you first start out with Gobi Manchuran which is fried cauliflower in a wheat based crust cooked in a spicy tangy suace of tamarind, chili, and other spices.   Next try the Chola Batura which has an amazing presentation and it essentially chick peas and a large pure, which is a giant fluffed bread.
