Just finished a two night stay there. To answer AJs questions upfront:

1. I was booked at a corporate rate of 7800INR+tax and upgraded, the final amount incl tax was 10800.
2. Cafe or club, either was OK, we used the cafe on both mornings.

All in all I would say the HR Delhi represents value for money: the suite booking includes to/fro airport transfers, the processes work very well and they have pretty good staff. The checkin staff knew we were approaching and took us right to the room. The checkin formalities were quick in the room, some of us may not be comfortable with parting with their passport and CC for a while. As mentioned above, there is no mention of the cafe breakfast option nor the diamond amenity (or the points option), I had to specifically ask for it.
The decor is rather weird, I guess it was state of the art back then. The residences are not done yet, I suppose a victim of the current deflation. The 'suite' is rather small, I would call it a larger room. The website lists it at 40 sq m, which sounds about right.
The cafe was very nice, we liked the breakfast and dinner buffet a lot. The indian options for dinner were very good, but the quality reflected in the price per head.
