Yep, I use the online food ordering sites whenever possible because it reduces the confusion.

Both you and the restaurant get a record of what was ordered.
I generally don't use the ordering kiosks at fast-food places unless there's a major line because it's still faster to tell the person the order than to scroll through. When it comes to delivery/takeout - technology rules.
Especially when it comes to pizza/wings kind of delivery where it's easy to get a repeat-order.
