Hello! Today’s Burger King release is the Burger King Penta Cheese Whopper, launched in July. It builds on Burger King’s premium cheese burger, the Quattro Cheese Whopper, by adding a cheese bun so you can properly enjoy five kinds of cheese in a single burger. Priced at 9,700 won for a single in-store, it’s a limited-run item available through October 20. Since I love cheese, cheeseburgers, and the Quattro Cheese Whopper all the same, I ordered it without a second thought. So shall we see what it’s like?

Penta Cheese Whopper: Prices and Highlights
This isn’t an entirely new menu item, actually. It got a one-off test run last October, went quiet for a while, and then landed in stores nationwide this July. The big deal is that it stacks a cheese bun onto the existing Quattro Cheese Whopper, letting you taste all five cheeses in one burger. First, let’s check the price.
- In-store: single 9,700 won, regular combo 11,900 won
- Delivery: single 10,800 won, regular combo 13,500 won
A Quattro Cheese Whopper single runs 8,200 won in-store, so this is about 1,500 won pricier. As is always the case with Burger King’s new and premium lineups, the delivery price pushes a single well past 10,000 won. Order for just two people and, with delivery discounts, you’re nearly at the cost of a large pizza.

The exact reason for the sudden launch isn’t clear, but the ad visuals make it look as if Burger King had Lotteria’s Napoli Matfia burger, which similarly uses a cheese bun, firmly in mind. Just as the Napoli Matfia first arrived as a mozzarella burger, Burger King already has the Quattro as its go-to cheese burger. This time I went with the Penta Whopper as a combo. As mentioned, it’s on sale only through October 20. Burger King’s official app is also handing out a standard 7% coupon, so if the timing works out, even at the entry Welcome tier you can get the combo for around 11,000 won.

Now let’s look at how it’s put together. As I noted, this menu takes the Whopper, one of Burger King’s staples, uses the quietly popular Quattro Cheese Whopper as its base, and swaps in a cheese bun. So in practice, the one real difference is that cheese bun.

Copyright PAKOC https://pakoc.netThe Mozzarella Cheese Bun
As the bun’s look gives away, it’s similar to the one on Lotteria’s Napoli Matfia mozzarella burger. Mozzarella is laid on the bun and baked, so that signature texture comes through. That said, it doesn’t use a brioche bun; it looks like the usual white bun underneath.

Copyright PAKOC https://pakoc.netA Look Inside
So shall we cut it in half and look closer? First, as I slice through, the lightly baked bun gives a crispness you can feel right at your fingertips. A quick scan, though, shows nothing especially changed in the build.

Below that sit the Parmesan cheese sauce, American sliced cheese, the Whopper patty, and cheddar-mozzarella shredded cheese. Since it uses the Quattro Cheese Whopper as its base to let the cheese shine, no sauce beyond the cheese sauce goes in.

Copyright PAKOC https://pakoc.netOverall, apart from the bun, almost nothing about the build has changed. Rather than a variation on the Quattro Cheese Whopper, it’s more accurate to see it as an upgraded version. Aren’t you curious how much one bun can shift the flavor?

Copyright PAKOC https://pakoc.netTaste Test: How Does It Actually Taste?
Now let’s get straight to tasting it. The Napoli Matfia was a size you could grab easily in one hand, but this one is a Whopper at its core, so it felt a touch heftier. With that, I took a big bite right away.

Copyright PAKOC https://pakoc.netThe Difference the Cheese Bun Makes
Naturally, the distinctive bun is the biggest point of difference here. If you already like the Quattro Cheese Whopper, the lightly toasted cheese bun plus the cheese inside comes together so the cheese flavor is firmly locked in. Better still, that signature white-bun feel, one of Burger King’s weaker points, largely disappears, so I didn’t even envy a brioche bun.

ⓒ
Copyright PAKOC https://pakoc.netInstead of a dry, crumbly bun, the crisp bite is a nice touch. If you picture the cheese baked onto a pizza crust at Domino’s or Papa John’s, you’ll grasp this bun’s texture instantly. Perhaps for that reason, it also pairs surprisingly well with the cheese inside. As I ate, I kept thinking a garlic sauce alongside would have fit rather nicely.

Copyright PAKOC https://pakoc.netRegulars of the Quattro Cheese Whopper will already know this, but rather than eating it the moment you get it in-store, it’s a good move to have your fries first so the cheese inside has time to melt fully, then dig in. I ordered delivery, so the cheese had melted thick and gooey and there was no real issue.

Copyright PAKOC https://pakoc.netAdd a tomato sauce here and it might taste a bit like a cheese pizza, and a garlic sauce would suit it too. If you want an even richer cheese hit, you could pair it with the Big Dip cheddar sauce from the recently released Long Chicken Burger and turn it into a full-on cheese bomb. Just having the cheese bun stand in for Burger King’s disappointing white bun isn’t quite enough to call it a value pick, but at least I didn’t feel shortchanged.

Copyright PAKOC https://pakoc.netThe Saltiness Caveat
That said, my personal take is that the cheese bun itself was a bit better on Lotteria’s Napoli Matfia mozzarella burger, where the baked cheese was more generous. On top of that, since the base is the Quattro Cheese Whopper, which already has a strong salty-savory cheese edge, that saltiness feels unavoidable. If you prefer the clean, mild taste of a plain Whopper, this may come across as a touch salty.

Copyright PAKOC https://pakoc.netFinal Verdict
In a sense, it inevitably carries both the strengths and the weaknesses of the Quattro Cheese Whopper. Even so, the disappointing white-bun flaw is clearly gone and this is an upgraded menu, so as someone who loves a cheeseburger, I enjoyed it plenty. If you’re a fan of cheese-heavy menus, I’d strongly recommend grabbing a discount coupon and giving it a try. And if you’re visiting Korea, it’s an easy pick to catch before the October 20 cutoff.

Frequently Asked Questions
Q. How much is the Burger King Penta Cheese Whopper?
It’s 9,700 won for a single in-store, with the regular combo at 11,900 won. Delivery runs 10,800 won for a single and 13,500 won for the combo, roughly 1,500 won more than a Quattro Cheese Whopper single (8,200 won in-store).
Q. Which five cheeses are in it?
Parmesan cheese sauce, American sliced cheese, cheddar-mozzarella shredded cheese, and a mozzarella cheese bun make five cheeses in all. It’s the existing Quattro Cheese Whopper with that mozzarella cheese bun added on top.
Q. How is it different from the Quattro Cheese Whopper?
The one big difference is the mozzarella cheese bun. Using the Quattro Cheese Whopper as a base, it swaps the white bun for a cheese-topped, baked bun, taking the cheese count to five and adding a crisp bite with fuller cheese flavor.
Q. What does it taste like?
Personally, the lightly toasted cheese bun made it satisfying. That off-putting white-bun feel is gone, so the cheese flavor really lands. Just note that the Quattro Cheese Whopper’s salty-savory edge carries over, so fans of a milder taste may find it salty.
