There's one Aggarwal sweets in Delhi Cantt. He serves amazing Lassi for 15 bucks...One glass of that lassi and you will not have your lunch....IT IS SO FILLING.....And Purrfectly YUMMMMM.. He also proudly displays many stars ( Kapil Dev and some ministers ) having lassi from his shop....The Lassi rox..
Also many ppl have mentioned the Bhalle wala @ Bharat nagar Chowk in Delhi. It is equally amazing!!
