When I was in high school, part of the curriculum was a class where the final project was starting a small business. Most students did something simple like opening a cafe or restaurant at school. They'd serve the most basic, simple things, like instant coffee or sugar cookies. They knew they didn't really have to impress anyone, since they'd get a good grade pretty much just for doing the work.
This restaurant reminds me of the ones that popped up in high school. For $5, I got the exact grilled cheese sandwich I've been making at home since I was 8. I was expecting there to be something special about it, but it seems to be made with the bread and cheese I buy at Loblaws and are in my fridge right now. I really expect a restaurant that specializes in a certain thing to serve me a version of that thing that a child can't make in five minutes.
