From lunch to takeout at the Severance food court

Just as it is introduced as a great Severance food-court spot, it had a definite presence even within the special setting of a hospital. That showed a distinct kind of trustworthiness among Sinchon restaurants.

It suited everything from lunch and dinner to takeout orders for people you know, which is why it was a great place to visit for so many purposes ✨

Are the potato chips really unlimited?

The potato chips are unlimited!! That alone was honestly the best, haha. Being able to enjoy crisp, delicious potato chips without holding back was such a huge plus.

The potato chips were so good that I just kept reaching for more. Once you start eating them, they have that addictive flavor you simply cannot stop 👌

The Double Bas Burger’s patty-and-vegetable balance

The Double Bas Burger was a classic burger with a great balance of juicy beef patties and fresh vegetables. 📊

Because it uses real cheddar cheese, I could taste a richer, nuttier flavor distinct from ordinary processed cheese. 👌

Fresh vegetables prepared right in the store—butterhead lettuce, onion, and tomato—came together so that every bite tasted fresh ✨

The house sauce tied the patty and vegetables together, completing Bas Burger’s own distinctive flavor 💫

Hawaiian Burger Combo: sweet-and-salty appeal

What does the Hawaiian Burger Combo taste like?

The Hawaiian Burger Combo uses low-sodium bacon, which felt like a thoughtful touch that considered health, too.

A slice of pineapple added a sweet note to the salty bacon and cheese. It properly recreated the distinctive, exotic taste of a Hawaiian-style burger 👌

As a combo that even included a cola, it made for a hearty meal all at once—truly perfect for a meal ✨

Everything about it makes for a perfect Sinchon handmade burger experience ✨
