The Lake View Hotel in Ballarat does that. Waited ages to catch the eye of a waitress, she says do the QR thing. Tried it, unworkable piece of s**t. Went inside and ordered instead. Would have walked out if it wasn't such a hot day and there was somewhere else nearby.
Yeah you have to enter your phone number, credit card number etc etc, plus I couldn't find where to order a takeaway coffee on it, really annoying
