Complicated system and service.

I always enjoy Nandos and the quality and flavours of food. However, I was a bit let down by the system of placing an order via my phone (via the barcode on the table). The process is just too complicated and confusing. We were 5 together and tried doing it on one phone but the order got lost along the way of passing the phone around for each one to look at the menu items and select separately. We eventually gave up and went to go stand in line to order. We then proceeded to order and pay separately but for the same table. The food came out separately and one person was already finished eating when the rest of the food came out. There was no human to talk to on the floor regarding our concerns. Perhaps the system needs a bit of fine-tuning.
