Seongsu burger joint: fried whole shiitake burger at Bas Burger

Bas Burger Seongsu atmosphere and tablet ordering

The restaurant has brown sofas and wood-toned interiors, and every table has a tablet so you order contact-free from your seat. It has that Seongsu-style feel, with soft lighting making it cozy yet trendy! Picking your menu from your seat is easy.

It's also a comfortable space to enjoy a burger on your own. I think it works well for anyone looking for a solo meal in Seongsu or near Ttukseom Station.

Are the chips at Bas Burger really unlimited?

Bas Burger Seongsu has a self-serve chip corner where you can take as many crispy chips as you like. They taste freshly fried, you can help yourself to as much as you want, and sauces like ketchup and mayonnaise are ready too.

If the chips run out, just tell a staff member and they'll refill them with freshly fried ones right away.

They're great for nibbling before the burgers arrive, and perfect with beer too! 🍻💗 Free, unlimited chips, wow! I think this is a welcome point for anyone looking for good value in Seongsu. 💛

What we ordered at Bas Burger Seongsu and the prices

At Bas Burger Seongsu I ordered the Mushroom Burger, the Bas Burger Combo, a Bas Lager and a Chili Mozzarella Cheese Bar. 🍔🍺

• Mushroom Burger ₩11,700
• Bas Burger Combo ₩10,600
• Bas Lager ₩3,900
• Chili Mozzarella Cheese Bar ₩3,700

Chili Mozzarella Cheese Bar (3,700 won)

The Chili Mozzarella Cheese Bar is a side dish with stretchy mozzarella packed inside a crispy fried coating.

When I cut it in half, the cheese stretched out long, and that sight alone looked so tempting. The outside is crispy and the mozzarella inside is chewy, with a spicy chili flavor added on top.

The spiciness cuts through the rich, savory cheese so it isn't heavy, and you keep reaching for more! If you like cheese, order a Chili Mozzarella Cheese Bar with your burger. 🎀

Mushroom Burger with a fried whole shiitake (11,700 won)

The Mushroom Burger at Bas Burger Seongsu is a handmade burger with a whole fried shiitake mushroom inside. It's generously stacked with a beef patty, real cheddar cheese, house sauce, butterhead lettuce, tomato, grilled onion and the fried shiitake.

The savory beef patty, cheese and vegetables come together with the fried shiitake on top, so every bite was rich and full.

Bas Burger Combo customized with grilled onions (10,600 won)

The Bas Burger Combo includes a drink, so I ordered a cider (Korean-style lemon-lime soda)! I also liked that you can customize your Bas Burger. I swapped the raw onion for grilled onion! With grilled onion you get a mild sweetness instead of that sharp raw-onion bite, which I loved.

You can also choose the type of bun, so there's some fun in putting together a combination you like.

Bas Lager craft beer (3,900 won)

Bas Lager is the craft beer I had with the burger! I ordered the small 285ml glass, and a cold beer alongside the burger and chips went really well together.

Crispy chips with a cold beer, need I say more? 🍺

A Seongsu burger stop before or after a date or a Seoulsup walk

Bas Burger Seongsu is close to Ttukseom Station so it's easy to get to, and it has customizable handmade burgers and unlimited chips too!

How about a burger place for your Seongsu date course? You can use the outside terrace with your pet too, so I think it would also be a nice stop before or after a walk in Seoulsup! 💚
