Gurudwara Bangla Sahib, Delhi's biggest Sikh temple, welcomes everyone, no matter their station or religion, for a meal. The kitchen is open 24 hours a day, and is supplied and staffed by volunteers. Chapatis, dal soup, potatoes, and more, all for around 10,000 people every day. Anyone who visits can volunteer for simple jobs to help out with the production if they want to. Besides a temple and kitchen, the complex also houses a school, hospital, hotel, and a library. -via reddit
