School Lunch Restaurant

Lunch Restaurant (学食) is a restaurant in the School District 7 Underground Shopping Center that serves school cafeteria food. Its aptronym, Gaku Shoku, means Cafeteria or a dining hall found in schools

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 the city. Logically it should be cheap, however, since it takes the menus from many schools it is not uncommon for expensive food such as that coming from Tokiwadai Middle School to be part of the menu. The food is sorted by school, so other than the contents of the dishes, there are other reasons why these are chosen. For example, one wants to get into a school but cannot do so, 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, consisting of hairnets, gloves, protective clothing, and a flu mask.
