I was just there a week ago.
coming very early from a connection, I had to wait until check-in opens at 2.30p only, so beware. also at that time the security lines are massive, much better later before the LX flight, said the lounge warden and i saw myself.
LX lounge small, but ok. nice staff and some good sandwiches. decent drinks.
if you are *G, you may want to try the SK lounge. free wifi, and roomier. plus a smokers room if you care.
