If you had gone upstairs, you might have been pleasantly surprised. That line outside means fewer people inside. Yes, I imagine it can still be crowded, but when we passed through at peak time a couple of weeks ago, bypassing the massive queue, inside we found a couple dozen unoccupied seats to choose among, and minimal lines for the bar, no line for the buffet. It was nice, relatively quiet, and much better than the insane gate area.
