There is one at T2 arrival area. U can try. Officially it is for transit passengers only. But depends on person at reception.
Most cards with visa tie-up work here. BOB/SBI etc. Axis/HDFC/ICICI/AU/IDFC have their own system and won't work.
Infinia priority pass will work as well.
Arrival Lounges are also called Land Side Lounges. There are only two such lounges in India at the moment.
