I go to Seoul 2-3 times a year and have regularly since 2007. They have a shopping district in Itaewon (part of Seoul), which also has about every type of food you can think of. When I visit (on business), I usually go to Itaewon and go to an Irish Pub there and have a Guinness or 2 with some Irish food. It's just a thing I do. They also have a Pub called "Prost" and all the waiters/waitresses wear Kilts. It's sorta cool. All this to say you can get any type of food there.
The Taxi's are very reliable and cheap, unless you try to take a taxi from the airport - then they will be $100. Don't do it. Once you get to town, then use taxi's.
The Incheon International airport is beautiful. But it is a bit away from the the city center. Takes about an hour to get to center of Seoul.
I would suggest you pick out a hotel (I stay at the Grand Ambassador), that way you can get an "Executive Shuttle Bus" about $16 ea person and they take you to the hotel.
The Subway/Train system there is top notch. Imagine my surprise returning to Seoul from going there in 1977 as a young Sailor, now seeing the subway system having up to 6 levels underground with under ground shopping and Malls! I ride the subway/trains all the time when there. It is my way to get around, even though I have an International Driver's license and drive in most other countries that I visit. Not Seoul, thank you. It's the amount of TRAFFIC there, not necessarily the drivers, although all the little delivery scooters shooting across intersections and driving up on the sidewalks is unnerving.
I would strongly suggest you don't drive yourself. Again the taxi's are really good around the city. Money is simple: $1 = 1000wan. The prices are about par. In the shopping district, the price of a beer (Cass is their local beer) is about 2000 wan at a local hangout.
I travel up to the DMZ when I am there and train and help our soldiers who are stationed over there. Koreans like the US and usually the young people will talk to you.
They also have a "bullet train" that travels from Seoul to Busan/Pusan coastal area. That train hits 200mph on regular tracks and is relatively cheap to travel on considering the distance. It is very developed on the coast and frankly very expensive. If you go there, have a place/itinerary in mind.
There is simply too much to tell you so PM me if you want more info.
