You've only got to look at their menu (e.g. Baby Squid, Rabbit Varuval, Organic Black Cod, Achari Venison, Sea Bass Fillet, etc, etc, and NO Madras, Phal, Jalfrezi, Dhansak, Patia, Dopiaza, Kashmiri, Ceylon, Korma, Passanda, etc) to realise that this is a very upmarket Indian restaurant and not typical of you run-of-the-mill BIR.
It probably isn't too surprising that they don't use traditional BIR cooking methods...for better or for worse...depending on your personal preference, of course....
I think their prices probably reflect this too (being perhaps twice what you might pay for a run-of-the-mill BIR dish).
