jonaGarden is a family restaurant the Toaru Majutsu no Index universe.

The building is close to a electric distribution technology center, It is also a notable location for delinquents to gather and meet.

Chronology
The restaurant is used in the anime adaptations as the starting point for the Toaru Majutsu no Index storyline starts and where it begins to coincide with Toaru Kagaku no Railgun.

Level Upper Incidents
Chronologically, the restaurant first appears in episode 8 of the anime where it hast been noted, that it was being used by gangs as a rendezvous point for people to trade the Level Upper. Misaka Mikoto tries to deceive delinquents into handing information about the Level Upper, but she was forced by them hand all of her money instead which prompts her to electrocute them all. She then meets the leader of the gang, Elder Sister who challenges her to a battle but is swiftly defeated by her, after Mikoto is prompted to not take her lightly. This encounter causes a blackout in Academy City.

This does not occur in the manga adaptation, as Mikoto and Shirai Kuroko visit another restaurant called Benny's, and where Mikoto would later meet Kamijou Touma who tries to save the delinquents.

Toaru Majutsu no Index
The Toaru Majutsu no Index anime uses the restaurant for a similar scene above, Mikoto meets up with Touma in the restaurant again, where he tries to save the delinquents from her as he knows that she is one of the level 5 espers in the city. This scene is similar to the manga adaptation, however the restaurant where Mikoto and Touma meet are different.
