The "Hole in the Wall" is a term often used to describe a small, unassuming establishment, typically a restaurant or bar, that offers surprisingly good food or drinks. These places are usually tucked away in less visible locations, making them hidden gems for locals and adventurous visitors. In a different context, the "Hole in the Wall" refers to a project initiated by Sugata Mitra, an educational researcher. This project involved placing a computer in a wall in a slum in New Delhi, allowing children to teach themselves how to use it, demonstrating the potential of self-directed learning.
