Meh, I was there in July, and found it to be OK. Just OK though, not great, not terrible. The main area seating was full, with scarce seats in the long corridor part when you arrive, but got a table as another family left. Free drinks were OK, didn't pay for the premium selection, but of course you need to tip in any case. "Greek" salad had no feta in it, the stir fry was pleasant I suppose and coffee and coke machines worked as they should. I wouldn't rush to go back, but as I'm already booked in J for next summer's trip to MCO, I suppose I will.
I can't see that it is any better than the old terminal lounge. With the size of the new C they could have made some more lounge space for anticipated passenger numbers, surely ?
