If a plain burger is coffee, the white burger is TOP...
What catches your eye first is the secret sauce piled generously under the soft sesame bun. The white sauce spills out and spreads generously all around the burger.
Especially check out this visual. It's just one burger sitting on a plate, but the white sauce covers the plate so broadly it looks like the burger is standing on top of the sauce!
With so much sauce, every bite gets a smooth wrap between the ingredients, and it's even more obvious when you look at the cut cross-section — the combination of rich fillings and sauce!
Mmm... anywhere near me with a good white burger? Roaster Burger in Jeongja-dong solves that problem!

Before the food arrives
Dear readers of the Travel Encyclopedia, do you like white burgers? I really like combination pizza too. Let me go try it out.
What is the outdoor seating and date-night mood like in Jeongja-dong?
With this cool September weather, it's outdoor seating time in Jeongja-dong! A perfect after-work date spot in Jeongja-dong.
QR ordering and what is on the self-serve bar
Roaster Burger uses QR ordering instead of a kiosk. The self-serve bar has parmesan cheese, crushed red pepper, and sriracha.


Ordering done via QR, even more convenient than a kiosk! Self-bar check~!
Quickly snapped a photo while other customers were out! Even an anaconda(?!) couldn't resist Roaster Burger.
How does the white burger taste? The cold onion sauce
If you're at Roaster Burger, the white burger is a must!! I've tried all kinds of handmade burgers — brown teriyaki sauce, fiery buldak sauce, thick mayo — but a white sauce?! For the record, it has nothing to do with White Castle.

It's cold, not warm, but you can subtly taste the smoothly ground fresh onion flavor... slightly sweet, refreshing, and clean! Thinking it tastes like mayonnaise? Not greasy at all.
How is the combination pizza? A 10-inch pie packed with toppings




The freshly baked pizza came out right away too. Roaster Burger, the Jeongja-dong burger restaurant, has both burgers and pizza so there's no need to fight over which one to order? Go with a friend, one of each — promise me!

Vinyl gloves are provided too, but eating warm pizza with your bare hands is the real deal!
How to eat the white burger, and one drawback
Since the white burger needs to be eaten with the sauce, you have to cut it up carefully with a fork and knife... but the drawback is it's not easy to eat it Instagram-pretty! Go for it with hands already dirtied(?!) from the pizza.
Approved as a Jeongja-dong burger restaurant? Yes, approved!
Dipping the pizza crust in white sauce




The meeting of pizza crust and white sauce... need I say more!!


A man's honor is eating freshly baked pizza before it cools!! Bacon, paprika, cheese, corn... a 10-inch pie packed with toppings is plenty for a lunch. One more bite of combination pizza, let's go!
Before and after: how much was left
So good it hurts!
I've learned that proof of a good restaurant is an empty plate!!
