Restaurant for WooCommerce

Hi
1. Try your demo and in the popup window you need to add an additional zone layer with a dropdown list with custom cities. The restaurant is from Mexico. I want to have delivery only in 2 states (Mexico City and State of Mexico) and linked to those 2 states I want to add a list of custom cities.
2. Shipping is limited to Mexico as I mentioned, but since payment is with PayPal, I want to disable billing details to speed up the process.
3. Also at checkout I need a custom message box.
4. Suggestion for the demo restaurant, it is not possible to access all parts because of the closed hours. I could not add products to the shopping cart or continue with the process and evaluate the functionality of the plugin.

Thank you
