In a city with a fair amount of Indian restaurants, Udipi stands out with their amazing food. Udipi is restaurant that specializes in Southern Indian cuisine, thus it is all vegetarian. The food is well spiced and comes in filling portions. My personal favorite is the mysore masala dosa (potatoes and onions spiced with turmeric, coriander, and mustard seed and a chili paste spread on the dosa) and idli, which is spongy and delicious! Meals are prepared fairly quickly, so it is good for a hearty lunch during the week if you work or live in the area. Please note that there is a $15 minimum for credit card payments.
While Udipi is a bit off the path, it is very much worth the trek for this culinary delight.
