Ronrick,
Whilst I must say that the FCT as well as the FCL in Terminal A both merit a special stop (the one in B close to the central area I like less, the other one in B never been to), the MUC one is nothing special. Sure, it's nicer than standing around in the SEN lounge with plenty of people with square shoe tips, and the car service is very convenient - but that's about it.
For me, the real difference is made in FRA where you have a real sit-down dining area and the full bathroom facilities and more space all in all.
So, all in all, when I don't have a tarmac position, going straight to the gate and taking one of the free drinks and a newspaper there is actually just as good.
Happy landings!
