Think what you're referring to is the area past the bar and the food area to the left, past the bathrooms. Not sure I've ever seen this door open, but on Sunday, it was open. There's a light sensor on the door which suggests that it requires a fob to typically access, but the door was wide open this morning. It wasn't clearly accessible, so I didn't venture over there. There's also an outside area where I saw people eating and drinking last week, but not sure if that was a lounge?
