My college is right in front of sugar and spice bhowanipur and I have a detailed experience of this place.never have food in the restaurant below(in the ground floor) which sells fast foods and snacks like rolls, burgers because they often keep stale foods, that has not been sold for 2 days or more.
I once had a chicken burger with one of my friends, while having it I could feel its not fresh and then both of us had got diarrhea.after that day onwards I never have food there.and my friends also dont go there.but I think the restaurant in the first floor is good where u can have lunch or dinner.till now no bad experience about the restaurant in the first floor but dont have those fast foods and snacks from the ground floor otherwise u will repent.
