It's going to be on the river, kind of opposite Centum city I think.
Yes, that's true. The nearest landmark is going to be the bridge that has the giant Busan Arch (the official name is?) over it. On the Suyeong side of the river, opposite The Sharp (The #) Centum Park apartments, drive past this (toward Dongnae, away from the ocean) and take one of your next few left hand turns. At the next corner, take a right and drive about two minutes (this road angles slightly away from the river) up the road. It will be on your left.
As for subway station, I would have to say that Suyeong will be your closest subway station. The Costco isn't really a quick walk from there. I would likely take a taxi (I live right behind Suyeong Station). Your best bet in this case would be to go out exit number 5 and then hail a taxi. Go straight about 2 minutes and you'll see a GS25 Gas Station on the left. That's where your taxi should turn. It should continue straight on that road, going past the Busan New Taxi parking lot. At this point you'll either go straight (great) or turn right (still no worries). If you turn right, you'll dead-end at the river and will then take a left. From this point, you should use the directions from the first paragraph.
If you went straight after hailing a taxi in the last paragraph, you will continue down to an awkward four way intersection. At this intersection, you want to go straight/rightish (the road you're heading on to isn't exactly straight across but that's the best I can give you). Then, drive straight for 4-5 minutes, it'll be on your left.
I realize these directions seem convoluted and I agree that they are if you haven't been back in that area. But once you actually go there, you'll see it's quite simple. As I said, it's not within a quick walk, but would probably take you at least a 1/2 hour your first time. After that, maybe you could figure out a shortcut.
http://map.naver.com/?lat=35.1753091&l...2&mapMode=0On this map link that I have posted, the arched bridge is 촤수영교. You should take a left after that and then your first right. The Costco will be on the left hand side of that road, just past the Steelworks (거려제강) and roughly across from MiGwang Taxi (미광택시). If you move the map up, you'll see Suyeong Subway Station and to the right of that, up the road a bit, you should see the stylized GS for the gas station turn off that I mentioned.
Wow, now I think that I'm turned around. If this is not clear, please post specific questions and I'll do my best to clarify how to get there! Maybe I'll run Costco tours from the subway station and back!
Cheers!
