Sitting in the VIE lounge now - at check in, was told that it was the grab and go back and you couldn't eat in the lounge. I think things likely changed with Austria easing restrictions and she just didn't know. Lounge has a full lunch spread, with hot food being served. Full bar also available for self-serve. The lounge is not full, but it is more crowded than I thought it would be (there are also more destinations on the departures board that I thought there would be - but this is my first flight since July 20, so what do I know?)
