Perth's Central Business District, located on the northern shores of Swan River and northeast of Kings Park, is a well concentrated area of both nightlife and cuisine. Crammed into the three blocks that separate Wellington Street and St. Georges Terrace, all things contemporary food and drink await the type of traveler who values a bit of selection after you've just dropped from 14,000 feet into Langley Park. The Aviary's rooftop bar on William St. is a must, the Cheeky Sparrow's casual ambience and good wine is inviting (Wolf Lane), and dance clubs like Ambar and the hip Deville's Pad are great places to enjoy music on the weekends.
As far as food, an international selection is packed into the area, with offerings like tapas, sushi, Australian specialties, and the ubiquitous and trendy cafes (Tiger Tiger and Greenhouse are the cream of the crop). Fully covered within an hour of walking about, you'll find your cuisine and nightlife needs easily fulfilled in Perth's CBD.
