Turkish pide (pronounced pea-day) is a quick bite similar to a calzone. Pizza-like crust enfolds fillings such as spinach, olive and feta, or chicken, mushroom and cheese. Say yes to a slice of lemon with your pide - squeezing it over the slices brings out the flavours.
Kebabs are also a popular lunch or late-night meal, and are usually available in beef, lamb, or mixed fillings. Watch out for additions such as cheese, tahbouli, and garlic sauce - these are often an extra 50 cents each. Still, kebabs and pide are one of the cheaper options to fill you up, and don't require you to get a table and sit down for an hour.
You can find both in the food court at Harbourside along Darling Harbour, but if you have more than 10 minutes to spare I recommend a quick walk to Pyrmont Kebab at Pyrmont Bridge Road & Union Street. It's just past the Pyrmont Bridge Hotel pub, and it's open late.
