Quick Service Restaurant Checkout

Hey Salman, maybe you can provide a little bit of context or the current UI of subway for reference? That will make it easier for me and others to review :)

For now, at first glance, few little things:

1. In order summary page, you normally want to reduce as many friction as possible as that's the last step your user would do before swiping their card. So remove the header on the top, remove the Subway banner, maybe allow users to search for address and automatically populate the information rather than manual inputs?
2. On the right, you can show image beside the name of the items to help the user to make sure they are ordering the right thing.
3. Think from business perspective, this is the last chance you can increase your revenue, what other features you can add to increase the chance that the user would buy more stuffs?

Good luck!
