My favorite was when they had macarons on the first day!
The meals are mainly planned around what would give the students the energy they need to study, but the nutritionist also considers what meals would make the students happy. Physical health is important, but so is mental health. We often have street food for lunch, like spicy rice cakes and fried foods. One day, we even had a tornado potato! The students have a lot of stressful things going on, but they always have fun during lunch!
