Bumping this...I just discovered the Turkish lounge while on a return flight from MIA and recommend it as a nice option if you have *G status. As others have noted, the food is decidedly mediocre (aside from the egg salad sandwich, which was really good), but it has nice seating and wasn't overly crowded at ~11AM.
EDIT: This was on a "Cruise Sunday". No wait to get in, but the Delta SkyClub had a line 25+ deep down the concourse!
