Tablets on restaurants? --V2

I’m evaluating a concept for casual dining restaurants and want blunt feedback on whether this solves a real enough problem to get paid for.

The product is a tablet-based in-store ordering system for restaurants where customers can browse the menu, place orders all from their table.

The goal is average order value, reducing waiter load.

Would highly appreciate any and all feedback please
