Fast internet
Often called "the most wired city in the world," Seoul is packed with wireless Internet (Wi-Fi) hotspots and cybercafes. Internet cafes/gaming areas (called "PC bangs") offer cheap ($1/hr) online access. High-speed Internet service is found in hotels, airports and train stations-even subway trains will be wired in the near future.

Palms down, not up
When calling over a waiter or a service person, do so with your palms down, then flutter your hand up and down with your fingers touching. It's impolite to do so with your palms up, especially pointing with one finger-which is how Koreans summon their dogs.
Tipping
In general, tipping is not expected in South Korea, although Western-style tipping practices are trickling in at upscale restaurants, which may add a 10% service charge to the bill, and hotels, where it's advisable to tip porters around 100 to 500 won (10 to 50 cents) per bag.
Call 120 for information
The Seoul Metropolitan Government has set up a telephone line to help visitors and international residents. Call 1-2-0 for information about local events and festivals, hotels, public transportation and other general questions about the city. Operators speak English, Japanese, and Chinese.
