After visiting several LX lounges in both ZRH and GVA both during breakfast and rest-of-the-day hours, there is a very clear picture:

The C and SEN lounges are at least on par and in some aspects better than before under Gategourmet (probably related to the fact that it was impossible to make things even cheaper and maybe just now after takeover -- most of us remember that the lounges were great when the opened about a decade ago and then went downhill until they reached the bottom), the FCL has taken a massive hit quality wise concerning F&B. How this is supposed to convince the few who are supposed to pay high prices for the 3.5 senseless seats is unclear to me.
