I used the Adani Lounge at T2 Domestic Departures yesterday at Mumbai. There was a quick check in station just after security, another once you defend and another outside the lounge. Used my Infinia. Surprisingly the HDFC website has a PDF for all the lounges where Infinia is accepted and this lounge was not in the list. Travel Club Lounge (MALS) was the lounge listed. The Adani Lounge is also operated by MALS.
Coming the the lounge, it's quite big but still crowded. Food was not that great but a bit better that usual domestic lounges in India.
