You can start a fast food company in ur locality but first you need to understand the local fast food evironment, feasibility, competetors and how they work. If you can find a loophole in that market you can use it to your advantage to create a company.

E.g: in our locality we had roadside fast food sellers who sell at a low cost and luxurious fast food restaurants who sell food at a premium rate. Here there was a shortage of normal vendors in fastfood who sells food at reasonable cost with quality and clean mainataince. So with my consulation 4people started a fast food comapany and they are earning profits.

If you want any clarification or any inputs ping me
