I know I'm not adding anything new but I'm also disappointed about the removal of hot food in the afternoon.
I'm also disappointed that this wasn't communicated. I went to the lounge recently and decided to check my email before grabbing some food. Big mistake as I discovered that they had just removed the food when I finally went over at 15:05.
I guess I have to follow FT more closely. (I don't know if this has been mentioned already but I can only find salted Kettle crips these days... no more cheese or vinegar anymore. Instead they introduced some weird rice crackers...)
