Its famous for its chat and proximity to the Golden Temple makes it more popular among tourists. I have been to amritsar recently and trust me the bhalla papri chat is amazing here.
Its really a hygienic place, perfectly neat and clean. You should not try the pani puri, It will be better if you opt for aloo paneer tikki along with the chat. But you should go here only for these too. Otherwise its better to opt for other restaurants which have varieties along with taste in all things.Thanks!
