I will be in Sydney for the first time in January, for a little less than a week spread out over two visits (three weeks in Australia overall). I'll be alone, so my food options are going to be aimed toward semi-touristy, a mix of grab-while-sightseeing quick service and a few more leisurely sit-down meals.
My leisurely budget is A$300 excluding alcohol, for 11 meals: 2 breakfasts, 2 lunches, 4 dinners, 2 jetlag places at 3AM, and one end-of-vacation blowout meal. My leanings are toward European, Indian, Chinese, and Singaporian, dislike fusion, Japanese, seafood other than shirmp/crab/halibut, and have a moderate peanut allergy (peanuts/peanut butter bad, peanut oil ok) that tends to steer me away from Thai/Vietnamese/Cambodian. I'm staying at Darling Harbour, but will have a train pass.
Based on what I've been reading from a variety of sources, I've got the following list from which to narrow once I get there:
One Blow-out meal: Lunch degustation at Becasse
One Spanish/Tapas: Encasa, Capitan Torres, Raquel's
Two Chinese choices: Billy Kwong, Golden Century
One "I'm tired and it's near the hotel" choice: Chinta Ria, Zaaffran
Two other neighborhood dinners: Doma, Il Baretto, Tandoori Palace
Three cheap and iconic: Harry's, bills Darlinghurst, Pancakes on the Rocks
One pub lunch: Lord Nelson's
