Due to a diversion of LH415, I had the the 'pleasure' of visiting the new lounge last week and its really nice and large. As mentioned above its just one big lounge now, with a separate nook for F pax (who use the 748 FRA flight). You can board gates E10 thru 12 from there directly.

Sadly the lounge was super full, not one seat to be had around 4pm thanks to the departure of the FRA (the diverted MUC) and CPH flights. I stood around for a while hoping to get a seat and then abandoned my visit and went downstairs again. Food and drink are the standard US lounge fare, on par with IAD and DTW.
