Coincidentally I got one of those SMS based surveys to give my feedback on my lounge experience today. I scored it 1 (Very Disappointing) and mentioned, inter alia, the menu issue.
30 minutes later the lounge duty manager called me. I highlighted the menu issue and we had a long conversation about the food quality issues over the last 18 or so months.
He said he will ensure more menus are put out. So clearly there is a real disconnect around this issue.
