It is technically B1, but it feels almost like the ground floor haha. On weekdays it opens from 7 a.m., so it seemed perfect when you need somewhere to eat early, too! ![Bas Burger in the Yonsei Cancer Hospital food court](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-03-uphlk-792.webp) ## A bright, tidy burger restaurant atmosphere The restaurant is clean but has neon signs for a hip feel. Other Bas Burger locations usually lean more pub-like, but perhaps because this branch is in a hospital building, it felt a little brighter and tidier. ![Bas Burger interior with neon signs](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-04-1r3rn-900.webp) ![Bright, tidy seating at Bas Burger](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-05-1mzv0-900.webp) Pink lighting and deep wood tones come together for a casual but distinctive atmosphere. The long banquette seating and wooden tables even reminded me a little of an American burger joint. ![Wood-toned table seating at Bas Burger](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-06-dtryj-900.webp) ![Sofa seating inside Bas Burger](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-07-oyxdu-900.webp) The self-service corner had thin potato chips, ketchup, mayonnaise, and more. Unlimited potato chips!! There was no way I could skip them haha. ![Self-service corner with unlimited potato chips](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-08-d5p9j-900.webp) ## A shrimp burger with whole shrimp and wasabi mayo I chose the wasabi mayo shrimp burger, with whole shrimp and wasabi mayo sauce. I swapped the fries for onion rings and the cola for a milkshake haha. I have been drinking way too much cola lately ㅠㅠ ![Wasabi mayo shrimp burger with onion rings and a milkshake](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-09-1prf8-1200.webp) This shrimp burger really lets the whole shrimp make an impression. The wasabi mayo shrimp burger comes with whole shrimp, onion rings, butterhead lettuce, onion, and tomato. It is finished with wasabi sauce, teriyaki sauce, and whole-grain mayo. You can see plenty of green vegetables and tomato between the round bun, while the charcoal-grilled shrimp peeks out from underneath 👀 ![Shrimp burger with whole shrimp and vegetables](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-10-f2bmv-900.webp) Most shrimp burgers have a patty made of chopped shrimp, but this one was different because you could see the whole shrimp as it was haha. The shrimp was cooked over charcoal, giving it a smoky flavor, and the onion rings inside meant it did not miss out on that crispy texture either haha. ![Cross-section of a shrimp burger with whole shrimp and onion rings](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-11-1czbu-900.webp) The wasabi mayo and teriyaki sauce also worked together, and the sharp little kick cut through the richness nicely. In short, Bas Burger's shrimp burger stands apart from typical shrimp burgers in both looks and flavor. I liked it 🤤 I would probably order it again next time! ![Ingredients in the wasabi mayo shrimp burger](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-12-1e6k9-900.webp) ## The milkshake and onion ring combination It was my first time having a milkshake at Bas Burger, and I liked that it was milkier and nuttier than I expected. The shrimp burger I ordered alongside it was not too rich, so the shake worked well even without cola or another fizzy drink. ![Bas Burger milkshake and shrimp burger](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-13-187gt-900.webp) Unlimited potato chips and devilishly delicious onion rings haha. Putting the thin chips and chunky onion rings together made choosing sides alongside one burger even more fun. ![Potato chips and onion rings side dishes](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-14-1uq57-900.webp) The potato chips were crisp but had a slightly substantial feel. Their texture was more like baked than fried chips, so I thought they would make a really great beer snack haha. ![Side dish with a baked potato chip texture](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-15-10tyt-900.webp) ![Bas Burger potato chips and onion rings](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-16-j7aa9-900.webp) ![Crispy onion ring side dish](https://img.superchart.com/images/sinchon-wasabi-shrimp-burger/sinchon-wasabi-shrimp-burger-17-m6cdt-900.webp) The onion rings were fried incredibly crisp, with that crunchy, salty, devilishly delicious flavor haha. There were about five of them, but they disappeared in no time as I ate them.. ## Where it is - Bas Burger Yonsei Cancer Hospital Branch (바스버거 연세암병원점) - B1, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, South Korea - 서울특별시 서대문구 연세로 50-1 B1 바스버거 - 37.5607797, 126.9384876 - Google Maps: https://www.google.com/maps/search/%EB%B0%94%EC%8A%A4%EB%B2%84%EA%B1%B0%20%EC%97%B0%EC%84%B8%EC%95%94%EB%B3%91%EC%9B%90%EC%A0%90/@37.5607797,126.9384876,17z --- Superchart · https://superchart.com/en/@alley-glass-seoul/sinchon-wasabi-shrimp-burger/ · https://superchart.com/llms.txt
