I was in the ST lounge last Sunday morning, as a CO Plat/*G. It did have free unsecured wireless.

I also thought the spread of food was really nice. I had a bacon sandwich and a blueberry crepe, both freshly made and just put out. Made it easy to skip the lasagna on the flight. It was too early to look the wines and liquors, though. While the downstairs was filling up, the upstairs was almost empty. To me, it looked like the lounge was larger than any PC I've been in at IAH or EWR. Very nicely appointed, and an excellent lounge.
