The only time that FestHaus has ever "made sense" to me was this year at FearFest. It was freezing cold out, so it was a warm place to go, and the "Swiss Alps" atmosphere almost started to make sense to me. However, the food was a sad joke, because I had to take my meal back up to the counter as it was inedible.
In the summertime, except to possibly escape heat exhaustion, I have no idea why anybody would step foot in there.
