My first apartment, in a complex called Yongsang-1, was small and dingy. At the time, I thought it was average by Korean standards, and didn't complain. However, I learned later that it was subsidized housing for poor people. The walls were dirty, the paper was peeling, there were exposed, grimy pipes, and worst of all, the whole complex was infested with cockroaches, which no amount of spraying and bug traps could get rid of. I was not happy, but I spent most of my time at the Language Center and very little time at home anyways, so I was patient. Several other teachers had housing problems, and were put in similar apartments. I don't think the university intended to give us lousy, substandard housing. They weren't very well organized, though, and weren't prepared for all the new teachers they were hiring over a short period of time.
After about six months, I was moved to another complex, Yongsang-4. This complex was also subsidized housing, but it was much newer, and a much nicer complex. No roaches! It was closer to downtown, as opposed to Yongma, the apartment building across the river from the university, where most of the English professors lived. Yongma was supposedly a "luxury" complex, but the rooms weren't any larger than mine, and I didn't think the high-rise building was much nicer than Yongsang-4. It was also far from downtown, effectively isolating the teachers who lived there. I had a couple of opportunities to move to Yongma, and declined.
Andong is a small, agricultural city (pop. 200,000). Foreigners are rare, so there wasn't much socializing for people who don't like hanging around with Koreans. Fortunately, I did. (What's the point of going to Korea if you don't want to socialize with Koreans?)
Once you've seen the local tourist attractions (Hahoe Maeul, Tosansowan, and other cultural sites), Andong's main venues for socializing consist of lots of cafes and restaurants, three nightclubs, and a bunch of bowling allies. There's also the Andong Dam and Imha Dam, both popular picnic areas.
If you don't like Korean food, you'd have a hard time finding much choice of Western-style foods in Andong. The only Western franchise was a KFC downtown. There was also a Lotteria, which is a fast-food franchise imported from Japan. Lotteria has McDonald's-style food, but the hamburgers and chicken sandwiches tasted....different. The fries were all right, though.
There are other restaurants in Andong serving "Western" food, but the choices were usually (a) hamburgers (Korean-style -- the meat always tasted funny and processed), (b) "dancus" (breaded pork cutlets), or (c) Italian food -- spaghetti or weak lasagna.
You're much better off developing a taste for Korean food, which is quite good. (I particularly liked bimbimbap, yukejang, sangetang, and bulgogi.) For those times when I had a craving for Western food, I waited until I had an opportunity to visit Seoul or Taegu, and went to one of the large Western chains there like T.G.I. Friday's, Tony Roma, or Outback Steakhouse.
