One of Hong Kong's busiest areas, Central is particularly crazy at lunchtime, when office workers crowd the streets and eateries. Most restaurants have set lunches—generally good values—with speedy service, so everyone gets in and out within an hour. At night the norm is either a formal dinner or a quick bite followed by many drinks, especially in Central's nightlife center, a warren of cobbled backstreets called Lan Kwai Fong. Mostly known as a drinking hole with mediocre dining options, LKF has stepped up its game in the last few years with some serious restaurants, most of which are tucked away in commercial buildings, away from the hustle and bustle of the street-level bars.
For a wider array of choices, head up to SoHo, but be wary of where you go: a lot of these places are average in terms of food and service quality. NoHo is a bit more bohemian, with some excellent hidden, independent culinary gems, especially along Gough Street.
Admiralty, wedged between Central and Wan Chai, is home to large shopping malls, and much of the food is aimed at meeting the lunch needs of workers and shoppers. It's also home to several large hotels and their respective high-end restaurants.
Once a mainstay of the Hong Kong streets, there are now only a little more than 20 licensed dai pai dongs—that is, open-air food stalls specializing in various types of local dishes. These outdoor eateries are popular for their dirt-cheap prices, minimal service, and—of course—their awesome food. There's usually no English menu, so be prepared to point to the dishes at neighboring tables.
