I had a completely different situation last year. Checked in via QR (no account needed), ordered my drinks, got them quick, could also pay them with PayPal. The last thing was great because I hate waiting for a waiter to get my bill and pay it. And I could add tips in this 'app' as well. But maybe I was just lucky that my first experience with QR-codes in a restaurant was so positive.

I suspect that you are not the person who decides which feature will be implemented? So first I would try to understand how the management or a product owner normally decides which feature is next and which KPIs are used to make a decision. And beside that I would listen to the needs of my clients (I know that this sounds a bit too easy). Are they happy with the product? Do they wish something else? Is there a platform for enhancement requests etc. where you can match your idea or just talk to the sales-people as they normally know what clients miss in features.
