I have been visiting Udupi Restaurant in Munirka for over 10 years now and the food has never failed to impress me - Its ironic but a South Indian restaurant sells the most delicious North Indian food in Delhi!
The North Indian Mini Thali( at Rs. 160+ 12% Tax) is a MUST TRY and a superb deal for money.
The South Indian dishes are also great and cooked with less oil and spices in the right quantity.
Always willing and eager to go to Udupi for a nice dinner!
The place isnt very fancy though but in winters you can sit on the open terrace which is quite nice. However, it is advisable not to foray into the Chinese menu there. Stick to North-South Indian food.
