Where can I shop in Sydney and make a good food stop along the way?

I would split this into two half-days: the QVB, Pitt Street and the Strand for an easy central route, then Newtown or Paddington when you want smaller shops and a cafe stop. Markets run to different schedules and vendors change, so check the current operating day before building the whole outing around one. Plan lunch near the second area instead of travelling back to a city mall.
