Bennys

Bennys is a family restaurant introduced in Toaru Kagaku no Railgun as the family restaurant where Kamijou Touma and Misaka Mikoto meet for the final time before the beginning of the Index Arc. It only appears in the Toaru Kagaku no Railgun manga.

Level Upper Arc
Misaka Mikoto and Shirai Kuroko go the the restaurant to gain a sample of the Level Upper from the thugs that hang out there. While Mikoto tries to woo the thugs, Kamijou Touma comes into the restaurant to order a bitter gourd and snail's hell lasagna (苦瓜). He later interrupts the exchange to save the thugs from Mikoto, knowing of her status as a dangerous Level 5. The thugs chase Touma with Mikoto tagging along, still wanting the Level Upper, and leaving Kuroko with the bill.

Trivia

 * In the novels, the restaurant is never named. In the anime adaptation, the restaurant is known as the jonaGarden Family Restaurant where Mikoto runs into thugs twice: first for the purpose of obtaining the Level Upper, and second, just her hanging out casually immediately before Touma arrives.
