I was there on 7/24 and the part which was AGL earlier was open. No alcohol that day coz of dry day in Bangalore. I was flying international in the daytime so the lounge was virtually empty. They have temporarily changed seating arrangements to squeeze in more guests but it's definitely not enough to accommodate night flights. For next few months, expect the Bangalore lounge to be a zoo.
This said, hopefully once the renovation is complete, the new lunge will be nice.
