I didn't realize how ugly Korean cities are until I got to Taiwan. It isn't because of pollution, garbage, or anything like that. It's the lack of diversity. The cityscape of Korea is abysmal- every commercial area is generic to the point of being an oligopolist dystopia. Within any square mile in Seoul or Busan (the only two cities that matter), you know exactly what you are going to see, and I'll list the businesses now:
Tom's coffee, Angelinus Coffee, Starbucks, Boyd coffee, GS25, Family Mart, Baskin Robbins, Paris Baguette, Tous Les Jour, Mr. Donut, Lotteria, McDonalds, Ho Bar, and 30 of the the same 4 cell phone shops. It is MADDENING. Almost every Korean restaurant I've been to has either been a franchise, or has been cloned by other copycats in nearby locations. That doesn't necessarily mean the food is bad, but it means, once again, little variety to choose from or even to look at. Even mom & pop stores have trouble differentiating themselves- I mean, how can they when Korean food lacks variety? I'd bet that literally 40% of all Korean restaurants are either BBQ joints or fried chicken and beer joints. It doesn't take long for the cityscape to get mind-numbingly generic and repetitive.
Taiwan has a lot of 7-11s, other than that, it is commercially diverse and as a result, the scenery actually changes. There aren't too many American corporations everywhere, perhaps because they find it hard to compete with Taiwanese food and drink. Taipei has lots of open space, beautiful parks and trees, but in the end it's still a big city, there will be ugly districts and pretty districts. Taiwan was certainly a lot funner to walk through than Seoul. It is much smaller, and has a lot more character to it. A lot of the parks and tourist places like the memorial halls will have scores of young bboys working their moves at night.
Taipei is swarming with cockroaches and mosquitoes though. I mean actual cockroaches, as in the insects, not any specific demographic or race.
