Inside Bas Burger Seongsu: is it comfortable for solo diners?

The store was more spacious than I expected, so it was fine for eating with a friend, and I also saw people eating alone.

First up, the Greed Burger set!

Instead of the regular fries, we paid an extra ₩1,500 to switch to sweet potato fries🙌

Eating a burger together with a side definitely felt filling💛 And with Pepsi Zero on top of that, it was the perfect burger set combo!

THE Bas Burger, burger only, ₩13,100

We also ordered THE Bas Burger single, which is ₩13,100.

THE Bas Burger single

We ordered both the Greed Burger set and THE Bas Burger to share, and with the various side dishes together, the portion ended up being just the right amount to fill us up:)

Chili mozza cheese bar, ₩3,700

For a side, we also ordered the Chili Mozza Cheese Bar for ₩3,700.

If just burgers and fries feel like something's missing, this is a great menu to add on! That day we got to try a good variety, from the Greed Burger to THE Bas Burger, sweet potato fries, and the Chili Mozza Cheese Bar.

How the free potato chip self-bar at Bas Burger Seongsu works

This was my favorite part of Bas Burger Seongsu hahaha — you can keep grabbing free potato chips!

Free potato chips grabbed from the Bas Burger self-bar

I ate some before the burgers even arrived, and kept nibbling on them while eating the burgers too — since it's free and you can have as much as you want, my satisfaction level was surprisingly high 🙌

Self-bar with ketchup and mayo

Best of all, the self-bar also had ketchup and mayo, so you could dip the chips however you liked. Chips with ketchup is great, but personally, having mayo there too was really the best part hahaha. It's a place where you order a burger and end up reaching for the chips over and over...!
