Bas Burger Seongsu, a burger restaurant near Seongsu Station — the classic, no-frills burger here was really good.

I was craving a burger in Seongsu, so I went to Bas Burger Seongsu. It's close to Seongsu Station and also an easy walk from Ttukseom Station, so it's a great spot for a Seongsu date or a lunch stop.

Bas Burger Seongsu has several menu items, but I always end up ordering the Bas Burger whenever I come. This time too, I went with the classic — and it was delicious as always.
Why the classic Bas Burger with grilled onion wins

The Bas Burger is ₩8,500. This time I swapped in grilled onion, and it worked way better than I expected. The balance between the patty and vegetables was great, and with each bite you get both the meaty flavor and the sweet caramelized taste of the grilled onion.

Honestly, a simple burger like this tastes better to me than one loaded with a bunch of extra ingredients. The price is easy on the wallet too, so it's good for a Seongsu office lunch or a light meal.

If you want to enjoy a burger in Seongsu along with the atmosphere, Bas Burger is a solid choice. It's a good stop after a date around Seoul Forest or Ttukseom, and there are affordable options for a simple office lunch too. Next time I'm in Seongsu, I think I'll order the classic Bas Burger again.
Is the chili mozza cheese bar worth ordering as a side?

The chili mozza cheese bar I ordered alongside was ₩3,700. This one's good.

It's not fire-noodle level spicy — more like Shin Ramyun spicy, so it wasn't overwhelming. There's a slight sweetness typical of chili sauce, plus melted cheese that makes it savory and tasty.

The outside was lightly crisp while the inside stayed soft and moist — that in-between texture was fun.

I think it'd pair really well with a Coke, and the portion was bigger than expected, so I'd recommend it as a side to go with your burger.
The Hawaiian burger: for pineapple lovers only

The Hawaiian burger centers on a combination of pineapple, bacon, and patty.

There's only about one leaf of lettuce and not a ton of other vegetables, so it's an easy option even for people who aren't big veggie fans.

Best of all, there are two whole pineapple rings in it, so pineapple lovers will be satisfied. The sweet pineapple paired nicely with the meat patty and bacon.
