Seoul Special Forces city walk

Korea Seoul four days and three nights trip, I feel that I have basically gone to all the places that should be checked in, and the efficiency is quite good. I admire myself for being the first in WeChat sports every day. The food feels still better in China, and the clothes in the duty-free shop are not cheap. Day1 Morning 8 o'clock flight from Shanghai to Seoul, booked 2 nights at Crown Hotel and 1 night at L'Escape. The location of Crown Hotel is really good, just a few steps away from the subway station which is very convenient. Next to it is the Lotte Building, had a casual lunch, then walked along the big square, visited Cheonggyecheon, had Korean beef for dinner, which was not cheap but tasted very good, went to Myeongdong shopping street, didn't eat snacks, went to Olive Young, the alkaline water biscuits were delicious, regretted not buying more. Day2 Slept in, took a taxi to a coffee shop in Hanok Village, the photo spot on the 3rd floor is excellent. Walked around Hanok Village, went to Gyeongbokgung Palace, saw many people taking photos in Korean traditional clothes, watched the 12 o'clock performance, had ginseng chicken soup, I think it was just so-so, but it seems wrong not to eat it when in Korea. The street near Gyeongbokgung Palace is very artistic and you can take photos everywhere. In the evening went to Seong-su-dong Onion, the desserts were as good-looking as they were delicious. Went to Ader, went to Point of View, didn't shop enough. Had potato pork spine soup, to be honest, didn't have high expectations before going, but there was a Chinese aunt who came to take orders, recommended a set meal for two, lots of meat, very satisfying, cheap, recommended. Walked around Hongdae, lots of street performances. Day3 Comic street, just near the hotel, lots of graffiti, took some photos and went to Lotte Duty Free, there is a Chow Tai Fook, the price is very good but the good-looking styles were all sold out. Checked out and went to L'Escape, this is a designer hotel, booked a large suite, felt quite luxurious. Went to Sinsa-dong to eat honey rice wine, quite innovative, kimchi pork pot, mediocre, seafood pancake with fresh and large shrimp, just a bit greasy after eating too much. Went to Apgujeong, every store's style is so good-looking, simply can't see enough, checked in at the London Bagel shop, it was all sold out, too popular, luckily there is also one in Shanghai. In the evening went to Myeongdong to eat purle jang crab, afraid of not getting used to it, only ordered a small jang crab set meal, the mixed rice was actually not bad. Day4 Bought some snacks at the convenience store and went to the airport. Seoul is not big, many shops only open at 12 o'clock, but went to all the popular places, also ate the delicious food...
