Is the Grill’d Wagyu Wunder really worth A$22.90, or are you just paying extra for the word “wagyu” on the menu? What actually comes inside it? Is it a proper, juicy premium burger, or a standard cheeseburger wearing a fancy name? And with pickles, mustard and tomato sauce all stuffed into one bun, do those flavours work together or fight each other?
The Grill’d Wagyu Wunder costs A$22.90. It stacks a premium Wagyu beef patty with aged cheddar, dill pickles, Spanish onion, Dijon mustard, tomato sauce and egg mayo. It has 2,980 kJ (712 calories), about 39 g of protein, and a rich, tangy, cheeseburger-style flavour.
What’s Inside the Wagyu Wunder?
Forget complicated builds. This burger keeps the classic cheeseburger formula and upgrades the beef.
Notice what is missing. There is no lettuce, no tomato slice and no bacon. Grill’d keeps this one all about beef, cheese and sharp, tangy flavours. You can see where it sits on the full Grill’d menu with prices if you want to compare it with the rest of the range.

What Does the Wagyu Wunder Taste Like?
Start with the patty. Wagyu beef carries more marbling than regular beef, and marbling means flavour. Expect a richer, almost buttery beef taste, not the plain char flavour of a standard fast-food patty.
The supporting cast is built to stop that richness from getting heavy. Aged cheddar adds a sharp, salty edge. Dijon mustard brings a slow, gentle warmth rather than real heat. The dill pickles do the hardest work: their vinegar bite slices through the fat and resets your palate for the next mouthful. Tomato sauce adds sweetness, and the egg mayo keeps every bite creamy.
It tastes like a grown-up cheeseburger. Nothing smoky, nothing sweet and sticky, nothing gimmicky. Delivery reviewers back this up too, describing the Wagyu Wunder as rich but “not oily or gritty”. If you love the classic beef, cheese, pickle and mustard combo, the flavour profile here will feel familiar, just turned up a level.
The protein is the headline. At close to 39 g, this burger genuinely fills you up and covers a big share of your daily protein needs. The trade-off is fat. At about 47 g, this is one of the richer burgers on the Grill’d menu, and the sodium sits near half an average adult’s daily target. This is a treat burger, not a light lunch.
Your bun choice moves the numbers a lot. Nutrition databases put the no-bun version at roughly 536 kcal and only 5.7 g of carbs, which makes it a real option for low-carb eaters. Exact figures vary slightly between bun options and sources, so treat the table as the standard-build guide, not laboratory precision.
Wagyu Wunder Price: Is It Worth A$22.90?
A$22.90 puts the Wagyu Wunder in Grill’d’s top price tier. The Bonfire BBQ costs the same at A$22.90, while the Grand Brie costs $18.90. Big beef burgers like the Big Queenslander and The Almighty cost A$1 less at A$21.90.
One comparison helps. A Build Your Own Wagyu burger starts at A$14.90, but that is before you pay for cheese, pickles, onion and sauces. Add the Wunder’s full topping list and the gap closes fast. With the Wunder, you also get a tested combination instead of a guess.
Prices can vary a little by store and delivery app, so check the current menu at Grill’d before you order.
My honest take: it earns its price if you want the purest wagyu burger on the menu. If you simply want the biggest feed for your money, cheaper Grill’d burgers will fill you up for less.

Pros and Cons
Pros:
Cons:
Who Should Try It, and Who Should Skip It
Try it if you are a cheeseburger purist. This is your burger. Try it if you have always been curious about wagyu but found steakhouse prices silly. And try it if the Bonfire BBQ sounds too sweet and smoky for your taste.
Skip it if you hate mustard or pickles, because both sit at the centre of this build. Skip it if you want a light, fresh lunch; there is no salad in here to lighten things up. And skip it if sharp cheese is not your thing but soft, creamy cheese is. In that case, read our Bird & Brie article instead. Different protein, same cheese-lover energy.
Allergens and Dietary Notes
Based on Grill’d’s official allergen matrix (June 2026), the Wagyu Wunder contains:
Egg, from the egg mayo
Milk (dairy), from the aged cheddar
Gluten (wheat), from the bun
Sesame, from the traditional bun (the panini bun may contain traces of sesame)
A gluten-free bun swap is available. Be careful, though: Grill’d itself warns that its gluten-friendly options are not suitable for coeliacs, because burgers can pick up traces of gluten during preparation.
Wondering about halal? That question is about certification and preparation, not just the meat in the patty. We have answered it properly in our guide, Is Grill’d Halal?, so read that before you rely on anyone’s guess.

Not as it comes. You can swap to a gluten free bun, but Grill’d warns that its gluten-friendly options are not suitable for coeliacs because of possible cross-contact in the kitchen.
No. There is no chilli in this burger. The Dijon mustard gives it a mild, tangy warmth, but nothing that burns. Heat lovers should look at the Chilli Addict instead.
Same wagyu patty, same A$22.90 price. Pick the Wunder for a classic cheeseburger taste. Pick the Bonfire BBQ if you want bacon and sweet, smoky barbecue sauce, and do not mind the extra energy at 3,100 kJ.
