Cheongjin-dong??? What could they possibly taste like ## Ordering 1 set + 1 single, with unlimited potato chips while you wait > BAS Burger set / Double Bacon Cheeseburger After much deliberation, we picked 1 set + 1 single item. We're not big eaters ㅠㅠ ![Table with the set and single item ordered](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-17-10ie7-900.webp) While waiting for the food ![Unlimited refill potato chips, James Gam](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-18-1tm91-900.webp) James Gam... first time hearing that name! They've set out potato chips in one corner of the store. The fact that you get free snacks like this~~~ this is such a steal. ## How do the Double Bacon Cheeseburger and the BAS Burger taste? Finally, our order arrived! ![Double Bacon Cheeseburger set served at the table](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-19-quck2-900.webp) ![Close-up of the BAS Burger Double Bacon Cheeseburger](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-20-1lho2-900.webp) Gorgeous, right??? The Double Bacon Cheeseburger. Look at what's inside, seriously… the bun is super moist and soft, the bacon is crisped up nicely, and the beef patty has that char-grilled feel—delicious stuff filling my mouth haha ![Cross-section of the Double Bacon Cheeseburger](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-21-xidrd-900.webp) Packed full inside too. The BAS Burger. Probably the most basic one? Meat cooked evenly, veggies fresh. No notes on flavor, none. ![Ingredients inside the classic BAS Burger](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-22-o3cr6-900.webp) ### Swapping the topping to grilled onion and the side to onion rings Oh! And I swapped the topping inside for grilled onion. With grilled onion in there, it's so much sweeter with an extra savory kick! A very solid choice haha Onion rings. We swapped the set side for onion rings. ![Onion rings swapped in as the set side](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-23-1tgim-900.webp) Munched them down with ketchup! These were also seriously well-made, well-made. ### Free sauces at BAS Burger: mentaiko mayo with the potato chips At BAS Burger, they give you a bunch of different sauces free like this!! (Some aren't free.) We tried the mentaiko mayo sauce, and it was salty and delicious~! Dipping James Gam (the potato chips) in it especially was pure - bliss. They go so well together!!!! ## Final verdict on BAS Burger Euljiro Branch I thought it was just a handmade burger shop... but it turned out to be a handmade burger shop that just keeps giving. Had such a great meal, and the owner was so kind! Checking if the food tasted good, telling us the chips were refillable, looking after little details here and there. This was a place I'd personally wanted to visit for a long time, and I'm so glad I got the chance this time! Stop by Euljiro and grab a meal here~~!! ![Table after finishing the meal at BAS Burger Euljiro Branch](https://img.superchart.com/images/euljiro-bas-burger-onion-ring-mentaiko-mayo/euljiro-bas-burger-onion-ring-mentaiko-mayo-24-fbt6k-966.webp) A bustling, popular spot, confirmed~~!! ## Where it is - BAS Burger Euljiro Branch (바스버거 을지로점) - 11 Euljiro12-gil, Jung-gu, Seoul, South Korea (basement floor, Seer Hotel) - 서울특별시 중구 을지로12길 11 시어소호텔 지하1층 - 37.5656618, 126.9911768 - Google Maps: https://www.google.com/maps/search/%EB%B0%94%EC%8A%A4%EB%B2%84%EA%B1%B0%20%EC%9D%84%EC%A7%80%EB%A1%9C%EC%A0%90/@37.5656618,126.9911768,17z --- Superchart · https://superchart.com/en/@place-for-supper/euljiro-bas-burger-onion-ring-mentaiko-mayo/ · https://superchart.com/llms.txt
