Here is a 1917 menu (click on it to make it larger) from that hotel so we can figure that this may be similar to the menu from which they chose their meal. If they were like modern toy industry people I bet they drank a lot of those McAlpin cocktails. Prices certainly have gone up since that time. Most of the items on the menu were for under a dollar. (I checked an inflation calculator and $1 in 1916 is worth $21.95 today).
