The wife and I visited here over the weekend. It seemed very similar to the club locations in San Jose and Las Vegas.
It had a small but good selection of snacks, sandwiches, and soups. They brought out a few additional trays of fresh baked cookies while we were in the lounge. Complimentary full bar was available.
A second small self service snack and drink area was on the western side of the club by the windows.
We didn't check out the shower rooms but I noticed they had two of them.
When we went into the club British Airways passengers was using this lounge. Just after they boarded, the Lufthansa passengers started trickling in for their flight.
