Will have a 3Hr transit in FRA next week before boarding SQ25 back to Singapore.

Have passed through FRA 3 times already this year and have been distinctly underwhelmed by the lounges I ended up in (drab grey decor, limited food options, long waits for shower (ultimately unsuccessful ) and worst of all, just horribly overcrowded..)

But that was travelling in C and I am hoping for a better F experience. I assume the LH F Terminal is solely for their own pax and I wont be able to get into that, but would appreciate any advice on what the best lounge option would be. When I was there a couple of months ago I saw a Singapore (minor) celebrity sitting in the LH business lounge looking lost and miserable and with a SQ First Class boarding card sticking out of his top pocket so i am trying to avoid the same fate...
