Reminds me of the paranthewalla (an Indian bread) and maggiwala outside IIT Delhi who certainly had a huge cult following in 2000. He used to be so popular because he was the only vendor in town open at 3am serving hot paranthas to students. Very enterprising guy.
I remember cheddies at iitkgp gate serving maggi & snacks like that. those days the rumor was that cheddies has not been closed since it opened in 80s. anytime you go there you can find another sole having a sudden urge for late nite snacks.
