Dish feedback for restaurants?

[charlie_hockey]

I want to make it easy for customers to give dish level feedback. 

I figure this is possible through the the developer resources square provides, ex: 

Send POS orders to an app where customers signed in with say credit card details or some other way to match their order. then send them the itemized receipt and ask for a quick thumbs up or thumbs down per dish .. 

Any thoughts on feasibility / existing solutions / interest in this sort of solution?
