While the ice-cream machine is historical, I think that having the ocasional and not informed visitor see it can actually cause the perverse effect of letting them think that the war in the pacific was a pleasure cruise for the submarine force. Which would not only be incorrect, but also unfair to those who sweated under the depth charges attacks or even perished for their land.
I hope there are somewhere around the proper information shields, so s to make people realize the true story
