Doyle's has been a popular eatery for decades. I ate at the original restaurant twenty-one years ago on my first visit to Sydney. Today, there are three to choose from - all high quality. Fine seafood is what they built their reputation on. If you have never had John Dory, a very mild sweet fish, you should try it. Doyle's chefs are famous for how they prepare it. Pictured below is Doyle's at Campbell Cove.
If the weather is nice, enjoy eating out under one of the umbrellas.
The Don Quixote Restaurant was a wonderful dining experience. When we arrived around 6:45, the place was almost empty. By 7:30 the place was packed. We appeared to be about the only people in there not of Spanish descent. The Australian Spaniards were having a great time - obviously a local favorite! I ordered the vegetarian Paella (Paella - Spanish national dish). It was magnifico. The service was by career waiters. A selective, reasonable wine list provide the appropriate accompaniment. One of the finest meals of the trip! I want to go back. People watching was as enjoyable as the dining.

The restaurant is located in the Spanish Quarter several blocks from the Hilton. Regrettably, I did not take a picture. However, a business card is provided for your reference.
The AMP Tower Restaurant offers daily meals. However, if you are in Sydney on a Sunday, the luncheon buffet is the way to go. Expect a wide variety of excellently prepared food. But, the food can't compare to the 360 degree views on a clear day. Since the restaurant revolves, be careful about setting a camera or purse on the outer edge - it will leave you...:-)
