Best pizza and burger places that are unique to Auckland? And food markets?

My teenage kids and I are coming to Auckland from Welly and keen to try some delicious meals. The kids are, predictably, fans of pizza and burgers. We're all big foodies and appreciate great food, but not interested in fine dining. Also, are there any daytime food markets (we'll be there on weekdays not weekend) or cool food halls that are a cut above glorified food courts?
