Dhabas are rustic places to eat, a roadside cafe for everyone in India. Perhaps, more close to the heart of majority of India for dining out or a quick bite.
Notice the cooking-gas cylinders for home delivery on the left.
This ain't no MacDonald but tastier. Dhabas are not swanky places one would find in New Delhi or NYC. They are also not for faint "vestern" stomach.
The counter for this dhaba says "Pure Vaishava*** (Hindu stream/ thought/ school/ style) Punjabi Dhaba" in devanagari.
*** They are referring to ingredients and style of cooking, something akin to kosher cooking.
