Scan QR > select items > pay > select LN wallet > pay

Payment is slightly slower than Apple pay.

In new version they plan to make it smoother similar to Apple pay - just select LN and hit pay.

The QR is attached to the table so you see your order and dont have to interact with waiters when you want to pay
