I have been visiting Udupi at Munirka since childhood and just love the place. The food is great, be it South Indian, North Indian or Chinese. Though its a South Indian restaurant, the North Indian Thali is my favorite - Chinese is not bad either. The pricing is just right and you wont feel the pinch on your wallet after visiting this place.
Over the years they have installed A/Cs and improved the decor but if its a shady or a winter day you have the option of sitting in the open. This place is definitely worth a try especially if you live in South Delhi.
