Perth's restaurants and cafés reflect Western Australia's energetic outdoor lifestyle, with menus strongly influenced by the state's continual influx of European, Asian, and African immigrants. First-class food is matched by wines and beers from some of Australia's most innovative vineyards and breweries. A jacket and tie are rarely needed, and most places are either licensed (able to serve wine and beers with food) or BYO (bring your own wine or beer). Tips aren't expected, but leaving 10% extra for exceptional service is welcome.
