I visit the one in Bannerughatta road, This is one great place for north Indian dining, the restaurant is usually kept quite clean, but right now there is some repair work under way, so you have to walk next to an open drain to reach the place; but it is worth it... or if your the cringy type you can get a home delivery, though the service is quite slow and sometimes frustrating.
But the menu is quite expensive you usually end up paying 500Rs for two people, I know it sounds ok for 2 people, but its not a place with party ambiance... its like paying 200Rs for two people in a good Darshani. The food is good but its still costly right??
I believe they have about 4 branches in Bangalore... I am not sure how the other places are and you also get a special North Indian chats on Fridays.
PS: Try out there Mango, strawberry and choc Moose... its really great.
