@Adam I had access to two free breakfasts, one in the hotel and one in the lounge. I skipped the former, as eating after security is much more relaxed.
The hotel breakfast would have been great, but the lounge was perfectly sufficient with rolls, yogurt, fruit, hot and cold drinks, and the like.
The two key features of a lounge to me are cleaner toilets (than the rest of the terminal) and the chance to refill my water bottle. Free food is a nice addition and very useful, but doesn't seem to make the top of my list.
@Adam I seem to have expertly skipped the question itself... Yes, it was buffet. I generally prefer buffets.
