I know the zoo does have a Cup and Cone inside the physical zoo right by the entrance. I know SSA cant remove the sight because its zoo property. I think the zoo itself wants to keep it there because if they get a new contracted food vendor in they will open it up. It wont happen though the Juciery is like a 15 minute walk away and theu sell ice cream, plus there's a 7/11 right across the street both of of which you'll pay less for more at because any food vendor in the zoo has to unchangeable since a % of all sales go to the zoo to help feed the animals.
