Gangnam is the central district of the southern half of Seoul. Though Jongno and Jung to the north may claim to be the center of Seoul, in many ways Gangnam is the true center of both Seoul and the entire country, "immortalized" and parodied by Psy's infamous song "Gangnam Style". Believe it or not, fifty years ago this entire area was rice paddies and pear farms. Everything you see here has been built since then, the construction mirroring South Korea's economic rise.
Gangnam in and of itself is large enough to split into two main districts, Apgujeongdong and Cheongdamdong to the north, and Gangnam/Tehranro/Samseongdong to the south.
Apgujeongdong and Cheongdamdong are both by the Han River, and earn the distinction of being perhaps the richest neighborhoods in all of Korea. Posh cafes, brand name handbags, Mercedes and Porches, ritzy department stores, and rows upon rows of luxury brand clothing stores characterize this neighborhood. Unsurprisingly, many of Korea's movie stars and singers make their home here, and are occasionally spotted enjoying some Patbingsu or sporting new sunglasses. There is also a sizable nightlife scene here, though it is relatively laid back compare to the chaos that is Hongdae/Sinchon. Most of it caters to upper-class Korean teenagers and young adults. Strangely enough, the apartment buildings here look no different from the rest of the city; if anything, the apartment buildings here are some of the oldest and shabbiest looking. This can be explained by the fact that the upper-class elite who reside here are fiercely opposed to new renovations and expansions, as they fear an influx of new residents will drive housing prices down and make the area unbearably crowded.
Tehranro, in stark contrast, is a long avenue with many glass skyscrapers running along both sides. Nicknamed "Tehranro Valley", after Silicon Valley, most of Korea's hi-tech companies are headquartered here, such as Naver and Samsung. The east end of Tehranro is Samseong Station, which has COEX and Bongeun Temple. Seolleung Station, in the center, has a park with some ancient royal tombs. The west end of Tehranro is Gangnam Station, the busiest subway station in the country. The station opens onto Gangnamro, a futuristic avenue that is bursting with modern skyscrapers, high-end shopping (though not quite as high-end as Apgujeongdong), cafes, bars, restaurants, huge television screens, neon advertisements, and thousands of pedestrians drinking it all in. Strangely overlooked by many tourists and the Seoul Government as a tourist attraction, Gangnamro truly epitomizes the modern, hi-tech country Korea has become in the past 60 years.
- Bongeun Temple (봉은사, 奉恩寺) – Traditionally an important Buddhist temple with rich history in a rural outskirt of old Seoul, the temple is now the biggest, richest, and the most visited temple in Seoul as the area near the temple, GangNam, transformed from rice field backwater in 80s to the most ritzy and opulent borough in South Korea. The temple has impressive array of Buddhist buildings and sculptures, and it provides a quiet resting and pray place to tourists and locals alike in middle of skyscrapers and shopping miles.
- COEX, (Metro Line 2, Samseong stn). This very large mall is located in Samseong-dong, Gangnam-gu. This state-of-the-art complex was designed for international conferences, and holds 150 specialized exhibitions and 15,000 conventions/events a year. The centre also plays a role in promoting international trade by connecting international buyers with local businesses. A variety of stores and attractions can be found in the COEX including: the COEX Aquarium ; a large Western-style "luxury" cinema; the Kimchi museum ; a traditional video game arcade; a PC Lounge; hair and nail salons; a large bookstore with many Korean, English, and Japanese publications; and a pharmacy. There are also shopping options in COEX and include mens and womens clothing, jewelery, sportswear, souvenirs, shoes, and electronics. As far as food options, there is a large food court serving several types of contemporary and traditional food cafeteria-style, and western chains such as TGI Friday's, as well as restaurants, hofs and cafes located all throughout the interior and exterior of the COEX. The COEX is also directly connected to the COEX Intercontinental Hotel and the City Air Terminal. Yearly conventions at the COEX include online gaming conventions (such as the popular Korean-originated MMORPG Lineage), anime conventions, and auto shows. It is possible to spend the entire day in this covered mall without setting foot outside, which can be a blessing if very bad weather hits outside.
- Yangjae Citizen's Forest, (Sinbudang Line, Yangjae Citizen's Foest Stn). – You will find a forest on your right if you drive through Gangnam Street. It's a park with streams and a clear view of the sky. There are over 106,600 trees planted in it, and it's a very popular picnic spot for young students. A little out of the way, but accessible by commuter rail, and it's a nice way to escape the hustle and bustle of Gangnam.
- Seven Luck Casino, (Metro line #2, Samseong Station) . This branch is attached to the COEX shopping complex. The casinos are only accessible to foreigners (it is illegal for Korean citizens to gamble), so remember to bring your passport. Various card tables and slots are available to play. There is a bar and cafe that serve food and drinks, although expensive.
- 'LG Arts Center, 679 Yeoksam, 1 Dong Kangnum gu, Seoul, (Metro line #2, Yeoksam Station, Exit 7),  ☎+82 2 2005 0114.Modern, multi-purpose performing arts auditorium opened in 2000, features live musical, theatre and dance performances from Korea and worldwide. Visit website for performance schedule and ticket information. Underground parking is available.
- World Comic Convention, (Metro Line 3, Hangyeoul station), . Twice a month the SETEC convention center hosts Seoul's World Comic con Festival. Admission is 4,000W but the inside is rather bland unless you are extremely familiar with Japanese and Korean anime. Your best bet is to go during convention hours and mingle with the crowds of Korean teenagers in elaborate cosplay costumes dressed as their favorite anime characters. Most are excited to see foreigners and very glad to have their pictures taken. As mentioned, this convention only takes place twice a month, so check the website (Korean only) to make sure it will be in session while you are in Seoul. edit
Apgujeong (압구정), widely known as "The Beverly Hills of Seoul" is the land of luxury, brand name goods. International brands like Chanel, Louis Vuitton, Dior, Gucci and Prada sit alongside Korean designer brands.
- Hyundai Department Store, 429 Apgujeong-dong, Gangnam-gu, Seoul (subway line 3 Apgujeong), ☎ +82 2 547-2233, . Mo-Su 10:30AM-8PM. Main store of well-known department store chain. edit
- Galleria, 515 Apgujeong-dong, Gangnam-gu, Seoul, . A very popular upscale department store. Just several blocks away from Hyundai Department Store. Also has a branch in Seoul Station. edit
Near the Cheongdam Intersection lies the heart of the Korean shoe scene. Cutting edge shoe shops include Sue Comma Bonnie, Hyaang, Heels and Namuhana.
Apgujeong (압구정) is the upmarket area of Seoul. Walk around the streets and you'll see teenagers valet parking their new Benz or Audi, strutting their new designer threads, and looking generally, well, rich. That said, a lot of people who party here aren't necessarily rich and live far away. Apgujeong is rather subdued when it comes to nightlife though it has a few posh clubs and bars. Places where valet is unavailable are unlikely to be great hits traditionally. There are, however, a few small clubs in the area. Expect English to be more commonly spoken in this area, too, due many Koreans in the area having studied abroad or received a lot of private tutoring. This has also meant, however, a certain desensitization to foreigners, so don't expect people to stare or approach you as much as they would in other parts of Seoul. Consider Apgujeong a great place to hang out, not party. If you want to impress a date for example, this is a great place to go to. The backstreets of Apgujeong tend to sprout and lose new clubs seemingly at random throughout the year, so getting off the main drag from time to time can yield a new "hot club of the month."
- Superclub Circle usually playing house music, sometimes hip hop(only availible for private parties as of July, 2009)
- Club Air House/Techno club.
- Elec Small, trendy club that is quite difficult to find.
Gangnam station (강남) is probably the No. 2 club area in Seoul. Also set up in a grid structure, clubs, bars, restaurants and other entertainment venues decorate this upmarket location. While not as upmarket as Apgujeong, it definitely is busy and lively. If Apgujeong is the place for rich kids to hang out and look cool, Gangnam is the place for those rich kids to party and look sexy. The station is a transit hub and a ton of buses run through the heart of the entertainment area, so finding your way there is extremely easy.
