@MuneneInc I'm not the biggest biryani fan either but I had some banging biryani from Bibi's Swahili Kitchen on @andodelivery. Maybe you should try it before you right biryani off completely.
Brilliant idea.
Suggest that you first look at Ando Kitchens model deeply. Then scale. It has very little to do with product which is already incredible and more towards the ops and processes. Get this right and you win.
Plus check Mama Rocks as guide as well.
