Greed Burger and wasabi shrimp takeout in Sinchon: Bas Burger

In short

Bas Burger Yonsei Cancer Hospital Branch is a handmade burger restaurant in the B1 food court of Yonsei Severance Hospital in Sinchon, Seoul. Two burgers alone with no sides, the Greed Burger and the Wasabi Mayo Shrimp Burger, were ordered at the kiosk and carried out in paper wrap, and the juicy patties and packed fillings were clearly a step above franchise burgers. The unlimited potato chips come only with dine-in, so the next visit at Bas Burger means eating in with the pollock roe mayo sauce.

I found a Sinchon spot that does homemade burgers without breaking the bank! It's in the basement food court of Sinchon Severance Hospital, so it's super easy to drop by. Let me introduce this Sinchon restaurant.

So many burgers looked delicious~ I agonized over what to pick! I ended up ordering the Wasabi Mayo Shrimp Burger single and the Greed Burger single. Lately I actually prefer two single burgers with no sides, haha.

Unlimited potato chips at Bas Burger are dine-in only

Above all, Bas Burger's signature is this chips! Unlimited refills when you order a main menu item — dine-in only, since takeout requires buying them separately. I ordered takeout so I didn't get to try them separately. Next time I'll definitely eat in for this.

With so many sauce options and warm, crispy chips, they're apparently very popular. You just keep picking one chip after another and it's gone in no time.

The side menu also looked really good~ I only ordered singles this time, but I want to try the sides next time. Burgers and fries are just an inseparable combo after all!

Two burgers wrapped in paper for takeout

How the Greed Burger and Wasabi Mayo Shrimp Burger tasted as takeout

They wrapped everything neatly in paper. The burgers are so plump~ really packed full inside.

The patty is clearly different! The juicy patty paired so well with the fresh vegetables, really delicious. The Greed Burger lives up to its name — the filling is greedily generous, haha. I always get curious about anything labeled 'jumbo' or the like and end up ordering it to see just how big and loaded it really is... and the Greed Burger really is huge and hearty. The patty was extra juicy too, which made it even better!

I've been eating so well lately that I've packed on some weight and am trying to manage it, but since I skipped the sides and only had the burgers, I'm counting it as a diet meal, haha.

The Wasabi Mayo Shrimp Burger's combo of shrimp and wasabi mayo was really good too. I love both shrimp and wasabi mayo, so I enjoyed it a lot. That sharp wasabi kick pairs so well with the shrimp.

This Sinchon favorite, Bas Burger, is a great pick when you want a simple but filling meal!
