The ISKCON Temple in Delhi, officially known as Sri Sri Radha Parthasarathi Mandir, is not just a spiritual hub but also a place where the food served has a deep spiritual significance. The temple adheres to the Vaishnava tradition, which promotes vegetarianism as a means to ensure a sattvic (pure) diet that is conducive to spiritual development. The food served here is first offered to the deities in a ritual called "Bhog" and then distributed among the devotees as "Prasadam". This sanctified food is believed to be a means of grace and is consumed with reverence. Over the years, the temple has become known for its delicious vegetarian cuisine which is prepared without onions, garlic, or mushrooms, following strict spiritual guidelines.
Note that all food served and available in and around the ISKCON Temple is strictly vegetarian, adhering to the principles of Vaishnavism, thus excluding any kind of non-vegetarian food including eggs.
