For a little while early this year, BA was using the small room right at the top of the stairs (i.e., stairs leading upto the ITC Maurya Sheraton lounge); it was the room to the right just before the door to the restaurant that you come across right before entering the ITC Maurya Sheraton lounge and it seemed a carve-out from the restaurant itself. [I don't know who is using that additional seating area as of late or not since I've been able to cut my arrivals down to just in time (due to special circumstances).] I'll try to check out things myself more next week.
