Aviserv lounge is on the left of Gate A to exit the airport terminal on arrival.
I have found Aviserv to be very very adequate (not great) but absolutely adequate.... you get a place to sit in comfort and quiet... you get hot food... eggs, dosa, rotis, parathas etc. made to order. What I don't like about the lounge is a couple of stupid policies.... 1. you can get only one type of meal eg: only breakfast or only lunch... so if you come 1 hour before breakfast ends you can't have the lunch afterward... that's as stupid as a policy gets. 2. they're the only lounge I know that charge for coke. I'm absolutely fine resting & eating there.
Yeah it's no Adani lounge... then again that's not what my expectations were to begin with.
