An old college friend of mine recently posted this on Twitter:
Ok, here it is. Until someone else comes up with something better. A crowdsourced sheet for street food. RT! https://t.co/QO9BcxlAGx— Thejaswi Udupa (@udupendra) April 5, 2016
I spent some time (and Whiskey) creating a user-friendly search for it, and I think it's in a presentable state now. Here:
Bangalore / Mumbai / Chennai / Pune / Hyderabad / Delhi
Contribute places as well, and get in touch if there are alternate spellings for places or foods (like kabab/kebab), I can add those in immediately.
