Yongsan is in Seoul's geographic center, sandwiched between Seoul's two major cultural and economic centers, Gangnam and Jongno/Jung. The main area of interest here for travelers is Itaewon, the most international and foreigner-friendly neighborhood in Seoul, and one of the only places where you can find authentic Mexican, Turkish, Middle Eastern, and Indian food on the entire peninsula. It has Korea's only mosque, markets hawking souvenirs and cheap t-shirts, Turkish ice cream parlors, and a nightlife scene dominated by foreigners. This may be partly due to the presence of the nearby US military base, which is also stationed in Yongsan. Other attractions include the National Museum of Korea, the War Memorial Museum, and Yongsan Electronics Market, a huge building selling gadgets at a steep discount.
For the time being, Yongsan is relatively quiet compared to its northern and southern neighbors, with many one and two story houses covering rolling hills and the southern side of Namsan. However, things may soon change; the US military base is going to be moved to a different location by 2013, and talks are finalizing on the construction of Yongsan International Business District, an incredibly ambitious $28.8 billion project involving dozens of supertall skyscrapers, including a 665m centerpiece, making it the second tallest in the world after the Burj Khalifa in Dubai. If and when this project goes through, it would utter transform the urban landscape of Seoul, not to mention Yongsan itself.
- National War Memorial, (전쟁기념관), (line 4 and 6, Samgakji stn). A museum about Korean military history and Korean War. Ancient, Middle Ages, and modern Korean weapons are on display. Also several fighter, bomber, and trainer aircraft which used during Korean War are on display.
- The National Museum of Korea, (Metro Line 4 and Jungang Line, Ichon stn). Houses the best of the best collection of artifacts and relics from across Korea throughout different periods and dynasty. Also has some West Asian pieces from Japanese Governor-General of Korea. Closed every Monday.
- I'Park Mall e-Sports Stadium, (Metro Line dark blue ,Yongsan stn). For a fascinating look into one of Korea's best subcultures, visit the top floor of the I'Park Mall neighboring Yongsan Electronics Market, where you'll find an e-Stadium. Here, professional video game players duke it out real-time on a enormous screen. Video games in Korea have been elevated into a sport, and there are professional leagues, mostly devoted to Starcraft, with matches that are, in fact, broadcasted on national television. Top players can earn hundreds of thousands of dollars a year in tournament winnings and sponsorships. A fascinating glimpse of Korea's new super-wired digital culture, and definitely one of the more interesting experiences to be had in Seoul.
Itaewon is Seoul's international district, with a wide variety of Western-styled venues to eat, drink and be merry.
- Yongsan Electronics Market. (Metro Line dark blue ,Yongsan stn)Yongsan Station is in IMall which is another huge shopping mall with two storeys full of electronics. Without negotiating you can have cheaper prices when compared to amazon.com. Yongsan is one option in Seoul if you are looking for electronics goods. Made up of over 20 buildings housing 5000 stores, you can find appliances, stereos, computers and peripherals, office equipment, telephones, lighting equipment, electronic games and software, and videos and CDs. A lot of the products are bought in Japan and resold in Korea by dealers. The market has a reputation for fleecing foreigners, particularly due to its proximity to the Yongsan U.S. Army Base. Be wary as Koreans try to avoid Yongsan for their electronics needs and rely instead on internet shopping as sellers in Yongsan are not averse to ripping you off if you don't seem to know a lot about electronics. If you go, it's best to bring a Korean guide so you can ensure you're getting a good deal. The problem is no or very poor English. Only Korean warranty. Cash prefered. At IMALL they add 5% as tax when you pay by Visacard. At Yongsan Electroland it dependes on the seller. Up to 10% addition is possible.
Since many foreigners congregate there, Itaewon remains somewhat of a niche nightlife area for Koreans interested in a more international scene. A number of notable bars and clubs spot the area, both on the main street and in the nearby alleys. Long notorious for being somewhat seedy, with prostitutes plying their trade and alleged (gasp!) drug dealings, Itaewon has become cleaner and more gentrified in recent years. Of course, this is by Korean standards - Western travelers, especially American travelers, will wonder what all the fuss is about. Due to Itaewon's proximity to the nearby United States Army base, a large number of American military are found there in the evenings and weekends. However, the US army has decided to move the base to a location outside of Seoul within the next few years, so expect regular changes to the area.
Many Itaewon shops, restaurants and bars cater to foreigners, and English-speakers in particular.
Many bars in Itaewon celebrate Thursdays as Ladies' Night, which often means that women drink free before 12am. There are also a few gay bars located two alleys east of the main street, with a mix of clubs and places to drink.
- Richard Copycat's All-American Diner, . Tons of great food and drinks. Serves authentic Buffalo wings and a great American breakfast (but not better than any of the five-star hotels in Seoul, just cheaper).

- Metro. A lot of older expats and many Koreans hit up this joint. Only one Korean beer on tap, but free pool.

They have the typical range of snacks available and free peanuts for beer drinkers.
- Bless U is another older expat haunt. You better be good with your pool game or you'll be waiting in a long line to go again. Darts are also available. They have great popcorn and decent draft beers. It changed ownership last year and has been running a tight ship since.

For some good house/trance music, try some places such as:
- King Club. Gaudy and a tad sleazy. Located in a seedy part of the neighborhood.
- Club Volume House/trance club, quite large and a excellent crowd on weekends. It is the best and most upscale club in the neighborhood.
