It's near Seodaemun Station Exit 2 and super easy to reach from Yonsei University too, haha. ![Walking route to Bas Burger Yonsei Cancer Hospital Branch near Seodaemun Station](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-01-we879-966.webp) It's on basement floor 1 of Yonsei Cancer Hospital, right by the arcade entrance, so it's really easy to find. ![Bas Burger storefront at the basement 1 arcade entrance of Yonsei Cancer Hospital](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-02-1404c-966.webp) Yonsei University students and staff get a 10% discount — kind of jealous of that, haha. ![Sign for the 10% discount for Yonsei University students and staff](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-03-j2xit-966.webp) ![Bas Burger storefront entrance signage](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-04-1l90s-966.webp) ## Kiosk ordering, free sauces, and a photo review event Ordering is easy via kiosk, and there's a really wide range of sauces to choose from! If you order a burger set or fried items (fries, wings), you get an assortment of sauces — so good, haha. ![Bas Burger kiosk screen showing sauce selection options](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-05-tw1pn-966.webp) There's a photo review event where you can get 2 pieces of mozza chicken bites or 1 cheese bar for free. The burgers look so good you'll want to snap a photo anyway, so I joined in, haha. ![Photo review event signage](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-06-v7x87-966.webp) ![Seating area inside the Bas Burger store](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-07-1danc-966.webp) We came in early on a weekend, so it was totally quiet and relaxed — loved that, haha. ![Quiet dining hall during early weekend hours](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-08-1e525-966.webp) ### Unlimited chip refills, dine-in only There are also unlimited chip refills in the store! No takeout allowed, dine-in only. ![Unlimited chip refill station for dine-in customers](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-09-1u3fr-966.webp) While waiting for our burgers, we munched on the free sauces and chips — crunchy and so tasty, and free too, what a steal. ![Free chips and an assortment of sauces](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-10-1934s-966.webp) ## What the two of us ordered We ordered: 1 Bas Burger set, 1 Hawaiian burger single, 1 mozza cheese bar. ![Table spread of Bas Burger set, Hawaiian burger, and mozza cheese bar](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-11-1v5jt-1200.webp) The moment we got the burgers, the buttery smell filled the air — so good, ugh. The lettuce and tomato looked completely fresh too. ![Cross-section of the Bas Burger showing lettuce and tomato](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-12-pd53j-966.webp) The fries that came with the set were pretty generous, so even with one set plus an extra burger for two people, the portion felt just right. With the free chips too, it felt even more plentiful! ![Generous portion of fries served with the set](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-13-17eid-966.webp) ![Table with burgers, fries, and sauces](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-14-1h7s3-966.webp) The burgers were also stacked so neatly and beautifully, haha. ![Close-up of the neatly stacked Bas Burger](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-15-1s2py-966.webp) ## How the Bas Burger tasted First up was the 'Bas Burger,' the most basic menu item, but the meat's savory aroma was amazing!!! The patty is seasoned quite saltily, and even with thick vegetables piled in, the flavor wasn't bland — it was perfectly balanced and delicious. ![A bite taken out of the Bas Burger showing patty and vegetables](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-16-i6edz-966.webp) ### Hawaiian burger — watch out for the pineapple juice Next was the 'Hawaiian burger.' I personally love pineapple in pizza and burgers, so whenever I see a Hawaiian burger on the menu I always order it, and Bas Burger's Hawaiian burger totally satisfied me! The pineapple was really thick and full of juice!!! The salty patty, bacon, and cheese combined with the pineapple's sweetness — so good... the ultimate sweet-and-salty combo, ugh. Just be careful, the pineapple juice can drip a lot, haha. ![Hawaiian burger with thick pineapple slices](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-17-3uncg-966.webp) ![Cross-section of the Hawaiian burger showing bacon and cheese](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-18-gxuwz-966.webp) ### Fries go best with ranch sauce Next we tried the fries — I personally love thick-cut fries, and Bas Burger's fries were so good! There were also many free sauces available, so it was great to dip the fries in different flavors. The fries plus ranch sauce combo was the best... free chips and free sauces, what a generous burger place, ugh. ![Thick fries dipped in ranch sauce](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-19-15zbc-966.webp) ![Fries with an assortment of sauces](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-20-2o514-m-966.webp) ## Is the mozza cheese bar worth adding? Last was the 'mozza cheese bar.' I'd been so curious about this cheese bar after seeing people eat it in mukbang reels and YouTube videos!!! The outside is red, kind of like chili oil, but the spiciness wasn't strong at all, haha. Freshly fried cheese sticks are just unbeatable... you could really taste the savory cheese flavor, so delicious! ![Stretchy melted cheese from the mozza cheese bar](https://img.superchart.com/images/sinchon-bas-burger-mozza-cheese-bar/sinchon-bas-burger-mozza-cheese-bar-21-gczvq-966.webp) I worried the cheese might snap short, but it was so hot it stretched out beautifully, ugh. Eating it together with the burger was such a great combo, haha. It's also a big size, so it's good for sharing between two — definitely recommend adding this one! Bas Burger tastes as good as it looks — generous and pretty. You really can't go wrong at any branch, but this Yonsei Cancer Hospital branch was the most satisfying in many ways this time!
