Carrols canteen
Carrols' lies next to the party halls in the building. Party-food support is gathering a lot of hungry party people and money. Those people must be hungry. Carrolls sells mainly small hamburger and French potato meal rations. The drink is Coke. For me their food wasn't enough to quench my hunger...
How much Carrolls' profit is after those 4 days? Count that, if they sold one hamburger or meal in 10 seconds with fee of approx. $ 4, open 24 hours a day...
But there is some food stores nearby in 1 km range from the party place, you could get some real food from there.
