There was a panel near the entrance, which could serve as a door to a toilet room, but there was no knob/handle/etc. There was a sign on it apologizing for construction, but the sign didn't specify what was being constructed (or that it was the toilet that was missing).
Off-topic...
This was our first trip to The Wing. We (the wife and I) walked unencumbered between The Haven (first?) and The Noodle Bar (business?) and back again. Where is the boundary between the first and business portions of the lounge? If first-eligible flyers are allowed to use both portions, what prevents business-only occupants from wandering into the first section. No one stopped/questioned us when we walked from one end to the other and back again.
interesting on both points. indeed there is a bathroom in there. the toilet was missing?! that's hilarious.
as for walking b/w business and first at the Wing, yea it's a major problem. I'm not sure why CX hasn't addressed it yet. It seems like every time I'm in there people are walking between the two. hopefully CX fixes this because it's a problem, and I wonder if it's one of the reasons the Haven is so crowded.
