Just back from 3 weeks in India...Too late your for specific question, but, perhaps for future Delhi hotel stayers:

Lots of negatives on service at Imperial. Personally had lunch at both Oberoi and Imperial and both had major service issues.

Did walk through the new, not yet opened Aman. It is already a WOW! Chic luscious contemporary with tennis courts, pools, huge spa, separate suite building with private plunge pools, balconies, private entrances. It's out of the immediate center location means a true oasis with easier ingress and egress and, scheduled to open in January, the daily Aman training has been going on since first of October.

And then, there are the terrific wildlife lodges in Madya Pradesh. Next year is the year when all 4 of the & Beyond/Taj properties will be complete. Tigers, Tigers, Tigers, trained in Africa guides and Nepalese providing "from the heart" service. Tres terrific!
