School Lunch Restaurant

Although Gaku Shoku (学食) usually refers to the dining hall found in a school, Gaku is the name of a restaurant that can be found in the Underground Mall, that literally serves school cafeteria food.

Principles
Due to the fact that Academy City is a city of schools, one can form a restaurant by choosing the best food from the canteens and cafeterias of Academy City. Logically, it should be cheap, however, since it takes cuisines from many schools it is not uncommon for expensive food such as coming from Tokiwadai Middle School to be part of the menu. The food are sorted by school, so besides the contents of the dishes, there are other reasons why these are chosen. For example, one wants to get into a school but couldn't make it, and so they want to eat the food that the school offers.

In the Toaru Majutsu no Index manga adaptation, the waiters and waitresses wear the same uniform as the people in school cafeterias, wearing hairnets, gloves, protective clothing, and a flu mask.
