With about a third of the population originating from "Elsewhere, Earth," you can correctly assume that Sydney is one of the best places to visit for a very diverse food culture. On one hand, some of the finest, Michelin-starred restaurants around can be found scattered about the city, particularly in Darling Harbour and the Rocks, while on the other hand some of the most inexpensive, culturally-relevant dishes can be found in downtown Chinatown and on certain trendy streets throughout the metropolitan area. Where to go, you ask? Well, that's entirely up to you.
As we have mentioned, the more sophisticated dining establishments will tend to be near the center of the city and by Sydney's world famous harbor, with Darling Harbour and The Rocks tending to be your place for more expensive, creative cuisine. The East Circular Quay in the Central Business District is also great for fine dining, although you'll have a number of other restaurants mixed in. Just be aware that you'll be paying (at the very least) a moderate amount for any meal in these more popular areas.
If you're one to avoid the splurge mentality, there is more than enough variety in Sydney to please any adventurer. There are a number of popular streets for grub that you'll need to be made aware of. The information is free; we consider it our civic duty. The first is King Street in Newtown (west of city center), ever-trendy and developing in response to the hefty student population. Thai, Portuguese, Chinese, and the rest of the world have real estate here, next to a bunch of little cafes and bakeries. Victoria Street in Darlinghurst is another street known for hip, moderately priced restaurants, and is home to everything from tapas to Italian to Argentinian. This is a great place if you just want to window-shop for a room full of chattering locals. Finally, Glebe Point Road, just west of city center, is another catch-all of great food that includes Nepalese, Chinese, Vegetarian, and much more. The only issue with this incredibly popular area is its lack of parking, making it a good idea to choose public transport if you're heading this way.
Then again, why eat out at all? Why not head up to the fish markets in Pyrmont (near Darling Harbour) and get fresh seafood? Or you can do the Aussie steakhouse shuffle. They're quite touristy, but you can slip just this one time for the sake of novelty. We won't tell.
