Multi-restaurant delivery website : are my desire possible with wix?

Hello ! I’m sorry if this is a little bit confused as english isn’t my native langage.

I’m creating for a friend a website for her new delivery business : she proposes to deliver your food order from local restaurant directly at home. I don’t have the premium plan for now because i need to be sure Wix can achieve what she needs BEFORE asking her to pay for the plan.

I’m actually using Wix Studio, with " Wix Restaurant Menu " and " Wix Restaurant Orders (new) " apps installed on it.

What i need to achieve :

• One page for each restaurant, displaying restaurant’s menu
• Clients may order directly from the website, and pay in it with Stripe
• I need to set-up individual opening hours for each restaurant
• and people may not be able to order things from two different restaurants/menus

What i’ve done for now :

I created my 5 menus on back-office with Wix Restaurant, one for each restaurant.
Example : “Sans Chaise” menu with different sections, “Fontaine” menu with different sections, etc. Each item is labelled with “home made”, or “vegetarian” but also with the name of the restaurant.

On wix studio, i now have two pages :
• My “Menu” page (from Wix Restaurant Menu app) is cool and clean, i can choose wich menu to display on it, i can display one menu on different page BUT clients can’t order on it. I don’t have any “add to basket” option, can"t see the option for each dish. It ONLY show the menus, but i can’t order. It is this page : https://livraisonbagneraise.wixstudio.io/accueil/commander-menus

• My “Order” page (from Wix Restaurant Orders app) is cool, it seems i can order on it as i can click and it asks me my adress, but it displays ALL the menus on one page. I can’t setup to tell “i only want this menu to be seen here”, i can’t duplicate the page to have multiple menu, i even tried to copy/paste the element on another page, it doesn’t work. It is this page : https://livraisonbagneraise.wixstudio.io/accueil/commander

Question :

I talked to a wix velo expert that told me that actually he’s not 100% he can achieved that even with velo code as he doesn’t know very well the Restaurant app limitation, neither displaying menus on separate pages, neither setting-up different available hours for each menu, neither setting-up the website for not being able to order in multiple menu for one order.

I REALLY need to be sure everything she needs can be made on wix, with built-in option or Velo-code.

Could you tell me if all of that is really possible ?
The business will start early september so i need to know now, if it’s impossible i need to change my CMS asap.

Thanks !
