Community College lunch/dinner was pretty good. It was basically a mock food court that served pizza, burgers, hotdogs, sub sandwiches, and different vegetable dishes every day. My only complaint was that the coke machine was almost always flat.
I ate at the university cafeteria like once and it was a similar experience.
In high school, our food resembled actual food but did not taste anything like what that food should actually taste like. My favorite combination was pepperoni pizza and hot grape juice.
