Yes, the famous Pind Balluchi restaurant is now open in Noida as well. It is situated on the top floor of the Unitech's Great India Place in Sector 38A (in front of Sector 18). Since the Lajpat Nagar's Pind Balluchi is now closed due to sealing done by government, this is the closest Pind Balluchi for Noida people.
The ambience is surely not as good as the original one in Lajpat Nagar but the food is still the same. Classic punjabi food and pretty cheap - to read more about what good there, have a look at http://gluttonous-me.blogspot.com/2008/01/pind-balluchi-lajpat-nagar.html
