Actually the main problem is that many regional brand's are already giving this in their states let's take a example of chakli who is famous in Karnataka , gujrat , Kerala , maharashtra , and Tamil Nadu so already 30-50 brands are selling their because demands are already created by thier old eating habits and if we introduce same thing in kanpur then few people's will definitely purchase but national level brands are already catering these Small demographics demands so the question is how we can change the eating habits of every city ? Providing authenticity is great thing but the main issues is people's will try 5-6 times but after that sales will drastically decrease because they love their foods according to their eating habits so providing them something that totally change their eating habits is the main revolution in food industry . Tedhe-medhe , kurkure and these types of snacks are famous because they invented something and created a whole new base of customers even researched on thier taste buds

Haldiram,Balaji and some other brands including ITC's products are already serving whole country... Aur abhi tak too yumm bhi apni jagah nahi bana paaya Virat Kohli ke hone ke bawajud
