I just had a Boom Chicken Whopper with cheese.
There were (likely better) free options in the lounge 10 feet from the BK, but there was no way I was passing that opportunity up.
It was a little spicy for me, but that's like saying the water was a little wet for me. I cannot handle spice.
Of course that made me sniffle and blow my nose, which is exactly what I love doing in airports these days.
