A few comments :
- On your delivery website, the first step is to choose a city, but you operate just in mumbai, so I can just select mumbai. If you could remove this choice before you open in new cities, it will make the flow of ordering one step shorter. It will also allow you to better market your local brand as the wording could be : order a burger in mumbai, ....
- The pizza ordering page offer images of the items to order, the burger page does not. Is it a deliberate choice? When ordering food I generally don't choose from unknown shop with no picture (but it's maybe a cultural difference as I am not based in india).
- You are operating on top of platforms (Swiggy/Zoomato), that can decide to move into the black kitchen business. Your only edge against that seems to be your brand, what are you doing other black kitchen are not doing to ensure that your brand get strong enough?
