You can only book a room if you are a member or through one. Excellent location, moderate prices, and very good food. Rooms are cozy. Ask for garden facing rooms in the main block. First floor is good. Centrally air-conditioned - a good thing in Delhi in summer.
Try the ginger pudding with custard sauce...very exclusive...or the apple pie - amazing.
The staff are nice, though regimented. They have greater than 80% occupancy through out the year - why care to smile?
