The best mutter paneer I've had till now was in a Dhaba or Roadside Shack, while driving from Patna to Darjeeling. We accidentally stopped by this place, cause the gas station guy filled "petrol" in our "diesel" car and had to be repaired. Yet the journey was very good, thanks to the lovely weather and the lovely Mutter Paneer.
The Mutter paneer was so delicious with freshly made phulkas (Indian bread), I can never forget the taste.
