we had ordered from OZ Pizza in Business Bay the other day. The great thing is they speak perfect, probably native english. Which is a huge advantage against the repeat your order 3 times and be still not sure of what you get delivery restaurants. As well the woman on the phone was extremely friendly.
Sadly the pizza we went for (BBQ Chicken) did not really match our taste. It was somehow strange, but that might be wanted through the Australian Taste. If you want to try them out yourself visit them on their website here: (LINK) or call them on 044313533.
