Iskcon Delhi is very Good place to visit in Delhi.
Specially. Purity and senctity maintain by its residence devotees. I have visited it. Visiting these give peace of mind.
The spiritual material and talk provide by its members is very clear and down to earth. Restorent provide very good food at very reasonable price. Unlike other no body ask for any donation. You can peacefully take Darshan of the lord. Would recommend one must visit it.
