Hope all doing good.
We have customised tastyigniter to support Dine In order.
Just scan the QR code placed on the table, Your menu appears, and place your Order. BINGO!!!
The order placed is integrated to our POS system, which informs the kitchen and cashier that an order is placed from which table. Its amazing. Please contact us for the demo. If you like it, we will put it up as an extension on github as well.
