In the DXB F lounge, what kind of food can I expect at 3am-6am? Any chance for some late night supper or will it just be snacks? any chance a la carte will be available so late? And is the free Spa treatment possible at such time? (I just read that it's open, but will it be like reduced services so the "free" treatment has to wait if someone wants to pay for it or something like this? never ever been there before..)

So many questions, I just try to maximize my DXB lounge visit
