Lotteria Ria Dutum Shrimp Burger Review [Korean Food]

Home » K-food Review » K-Hamburger / Franchise » Lotteria Ria Dutum Shrimp Burger Review [Korean Food]

Hello! Today’s Lotteria release is the Ria Dutum Shrimp, two versions, launched in July 2026. It’s an upgraded take on the beloved Ria Shrimp patty, beefed up so you get an even bolder shrimp flavor. At 7,900 won for a single burger, it dropped in two lineups at once: a basic horseradish-sauce version and a spicy-tomato-sauce version. I don’t order here all that often, but I was curious enough to try it. The moment I saw how thick the patty was, I let out an audible “whoa,” and the sauce pairings turned out decent too, so it was surprisingly worth eating. Let’s dig into what it’s all about.

Ria Dutum Shrimp: Price and What’s New

Lotteria says it launched this to let fans enjoy the patty of its signature Ria Shrimp in a thicker, more filling form. Bumping up the patty’s volume to maximize the flavor of the ingredients is the headline feature. As mentioned, it comes in two versions released together: one with the basic horseradish sauce and one with spicy tomato sauce. First, let’s check the prices.

Ria Dutum Shrimp (basic) horseradish, single: 7,900 won in-store, 8,800 won delivery (Coupang Eats)
Ria Dutum Shrimp spicy tomato, single: 7,900 won in-store, 8,800 won delivery (Coupang Eats)
Ria Dutum Shrimp (basic) horseradish, combo: 9,900 won in-store, 11,300 won delivery (Coupang Eats)
Ria Dutum Shrimp spicy tomato, combo: 9,900 won in-store, 11,300 won delivery (Coupang Eats)

It’s only 800 won more than the Ria Shrimp Bacon and 1,900 won more than the plain Ria Shrimp, so on a single-item basis it does feel a touch pricey.

I ordered the Ria Dutum Shrimp as a combo and the spicy tomato one as a single, so I could review both at once. This release is hefty right from the packaging. Eat both and your stomach will be seriously full.

Inside the Original Ria Dutum Shrimp

Let’s start with the original Ria Dutum Shrimp. The instant you peel back the wrapper, a thick shrimp patty on a completely different level from the old Ria Shrimp burger jumps out at you. That said, the sauce setup seems to have gotten a bit simpler.

There’s no official figure on exactly how much bigger it got versus the old patty, but by eye it looks at least 1.5 times thicker. You can feel it just from the photos, right?

A Look at the Cross-Section

Let me cut it in half for a closer look. For all that thickness, the build itself is pretty simple, so slicing wasn’t hard at all. I could feel the crisp-fried, thick shrimp patty even at the tip of the knife. From the top down, it’s mayo sauce, lettuce, tomato, horseradish sauce, and then that thick shrimp patty.

Compared with the original menu, the shrimp patty here doesn’t seem to use anything more unusual inside. It’s notoriously nicknamed the “pollock burger,” but there’s a reason it has staying power, so this feels like they simply scaled up the volume without adding or removing much.

Fundamentally, the patty packs whole shrimp pieces between fish and shrimp meat to keep some originality, and that’s its defining trait. It tastes a bit like fish cake yet with that distinctive shrimp mix, so I’d call it a kind of service menu for fans of exactly that flavor.

Inside the Spicy Tomato Version

Next, let’s look at the Ria Dutum Shrimp Spicy Tomato. Since the only thing that changed from the original is the sauce, I’ll keep this quick. From the outside there’s honestly not much difference, right?

Let me slice it in half right away. Versus the original, the red of the spicy tomato sauce, in place of the white horseradish sauce that sat between the veggies and the patty, is the first thing you notice. A quick taste suggests it’s not as spicy as you’d expect.

Since the shrimp patty itself can come off a little greasy, you could say this version trades the acidity that would cut that grease for a touch of heat plus the umami from the tomato sauce to lighten the load a bit. Everything else was basically the same.

Taste Test: The Original Ria Dutum Shrimp

So let’s start tasting with the original Ria Dutum Shrimp. It’s seriously thick, so I took a big bite. The overwhelming texture from a patty far thicker than the Ria Shrimp really was impressive. Because it’s so thick, the burger’s signature shrimp character comes through much more.

The Ria Shrimp also has whole shrimp in the patty, but it leaves you wanting a bit more; this one seems to win on sheer quantity. Sure, it still falls a little short of a true shrimp burger made with actual shrimp, but the upside is that the patty’s distinctive shrimp juiciness and aroma come through more intensely.

That said, the sauce here has relatively little acidity, so compared with the tartar-sauced Ria Shrimp it does get one-note fairly quickly. At times I honestly wasn’t sure whether I was eating a shrimp burger or just a shrimp patty. Still, if you liked Lotteria’s existing shrimp burgers, it’s the kind of flavor worth trying at least once.

Taste Test: The Spicy Tomato Version

Next I tried the spicy tomato one right away. From the first bite, the umami of the tomato sauce made it cling to the palate nicely. The sauce is billed as spicy, but if you expect real heat you’ll be a little “huh?” — the spiciness barely registers. I’m bad with spicy food, so if it’s mild even to me, anyone who prides themselves on heat tolerance will be let down.

Still, that faint heat does help tame the peculiar richness that the horseradish sauce couldn’t, and thanks to the umami the seasoning felt just right, giving it a moreish quality that kept me reaching for it. If I had to pick one of the two, I’d go with this one.

Final Verdict

Both burgers offer a build and a taste that will comfortably appeal to Lotteria shrimp-burger fans, but overall I suspect the spicy tomato side will earn the better reviews. After finishing both, I also felt the value for money wasn’t exactly great. If you’re going to order, dining in at the store beats delivery by a mile. For anyone who has loved the classic Ria Shrimp burger, it’s the sort of menu worth trying at least once. And if you’re visiting Korea and enjoy seafood-style burgers, you’ll find these at just about any Lotteria.

Frequently Asked Questions

Q. How much is the Lotteria Ria Dutum Shrimp burger?

A single burger is 7,900 won in-store. The combo is 9,900 won, and delivery runs higher at 8,800 won for a single and 11,300 won for the combo. Both the horseradish and spicy tomato versions cost the same.

Q. Which is better, the horseradish or the spicy tomato version?

Personally, I’d go with the spicy tomato one. The horseradish base has little acidity and turns one-note fairly quickly, whereas the tomato sauce adds a mild kick and umami that cut through the richness of the shrimp patty and keep you coming back.

Q. How does it differ from the regular Ria Shrimp burger?

The biggest change is patty thickness. It looks at least 1.5 times thicker, so the signature shrimp flavor and aroma come through far more strongly. The rest of the build stays close to the original Ria Shrimp, essentially scaling up the patty’s volume.
