While we didn't eat anything at the carnival the last two years we went, we got some food this year. Daisy was super-happy, I took her to the carnival right after work and she told me that she didn't eat yet when we got there. I think her smile is proof that her plan worked.
The main reason why we never got anything to eat there the last two years is that there is almost nowhere to sit. You can walk around with cotton candy and popcorn, but Daisy couldn't do the same with hamburger, fries, and a soda. Out of the whole place, I only saw two benches which were right next to each other. Fortunately one of them were empty by the time we got some.
