$7.99 buys the Dave's Triple a Grand Slam starts from; the fourth patty has no published price.
A Wendy's Grand Slam Burger, also called the Meat Cube, is four beef patties in one sandwich. The route is a Dave's Triple, priced by Wendy's at $7.99 for 1,100 calories, with a fourth patty added. No charge for that patty is published, so the finished total cannot be computed. On the listed menu the same step costs $1.00 to $1.20, which puts the build near $8.99 to $9.19.

How it works
Start from a Dave's Triple
Three quarter-pound patties are already there at $7.99. That is the part of the build nobody has to guess at.
Ask for one extra patty, by that wording
An added patty is a register option rather than a recipe change. Saying Meat Cube or Grand Slam gets a blank look, because Wendy's has never sold either.
Ask what the patty costs before confirming
This is the number nobody can give you in advance. On listed sandwiches the same step runs $1.00 to $1.20, so anything wildly above that is worth querying at the counter.
Say how much cheese you want
Accounts of this build split between a slice top and bottom and a slice per patty. Deciding for yourself avoids inheriting somebody else's version.
Go inside rather than through the drive-thru
Four patties take four spaces on a grill and a timed lane makes that awkward. Off-peak at the counter, the same request is unremarkable.
If something goes wrong
The nickname produced nothing
- Cause
- Wendy's publishes no secret menu and crew are trained on modifiers
- Fix
- Ask for a Dave's Triple with an extra patty. Those are buttons the till already has, so nothing has to be explained, argued for or looked up by anybody.
The extra patty cost far more than $1.20
- Cause
- Add-on charges are set locally and Wendy's publishes none of them
- Fix
- Query it at the counter. The listed pairs on this page value a patty at $1.00 to $1.20, which is the only benchmark available.
The kitchen refused during the lunch rush
- Cause
- A four-patty sandwich occupies grill space and slows the order behind it
- Fix
- Come back off-peak. A refusal at a busy moment is a scheduling decision rather than a policy.
It arrived with less cheese than expected
- Cause
- There is no standard build, so the crew used their own judgement
- Fix
- State the cheese count when ordering. Asking for a slice between each patty is a normal modifier request.
The calorie figure is impossible to pin down
- Cause
- Wendy's publishes counts for listed sandwiches, not for custom builds
- Fix
- Start at 1,100 for the Dave's Triple. On listed pairs a patty adds between 265 and 325, so expect somewhere near 1,365 to 1,425.
Two guides gave two different prices
- Cause
- Both estimated the patty charge and neither said so
- Fix
- Treat any single figure as a guess. The honest position is $7.99 plus an unpublished amount, and this page shows the workings for the rest.
What’s fixed, and what actually varies
One half of this is published to the cent. The other half has never been published at all.
Fixed
- The build is four beef patties in one sandwich, from a Dave's Triple plus one
- Wendy's prices the Dave's Triple itself at $7.99 for 1,100 calories
- An extra patty is a modifier the till already carries
- No Wendy's price list published a charge for that patty
- Neither Grand Slam nor Meat Cube is a Wendy's product name
Varies
- What the fourth patty is charged at, restaurant by restaurant
- The cheese count, which published accounts of the build disagree about
- Whether a franchisee prices above the figures Wendy's posts centrally
- Whether a busy kitchen will take the order at all
- How many patties people mean, since the name has been used loosely
Open a Dave's Triple in the Wendy's app with your restaurant selected and look for the patty modifier. Where the app carries it, the price appears the moment it is tapped and the guesswork on this page becomes unnecessary. Where it does not, the counter is the only place the question gets answered, and asking before confirming costs nothing.
A build priced to the cent, and then not priced at all
Among the chains covered here, Wendy's is unusual: it posts its own prices. That makes most builds easy to cost. This one is the exception, and the reason is worth spelling out, because it applies to every patty-count build on every secret-menu list ever published.
A Dave's Triple is $7.99 and carries 1,100 calories, both figures from the company. Adding a fourth patty is an ordinary modifier. What the company does not publish, anywhere, is what that modifier costs. So the honest total is $7.99 plus an unknown, and any guide quoting a single number for a Grand Slam has filled that gap with a guess, usually a tidy one that happens to match whatever the last guide said.
The gap can be bounded, though, using nothing but listed prices. Three burger families are sold in single, double and triple form, and the steps between them price a patty directly. A Dave's Double at $6.79 becomes a Dave's Triple at $7.99, so one patty is $1.20. A Big Bacon Classic at $6.69 becomes a Big Bacon Classic Triple at $9.09, which is $2.40 across two patties. A Pretzel Bacon Pub Cheeseburger at $5.59 becomes a Pretzel Bacon Pub Triple Cheeseburger at $7.59, or $1.00 a patty. So the menu itself values a patty at $1.00 to $1.20, and a four-patty build should land near $8.99 to $9.19.
One family had to be left out. Dave's Single shows $8.13, above the Double at $6.79, and that inversion is a fault in the company's own display rather than a price anyone pays. Leaving it in would have dragged the benchmark upwards by roughly a dollar a patty and made every derived figure on this page wrong in the same direction, which is exactly how a small data fault turns into a confident wrong answer.
Calories behave the same way. Those pairs put a patty between 265 and 325 calories, so the finished build sits somewhere around 1,365 to 1,425. None of that is a company figure for this sandwich, because no company figure for this sandwich exists. The Wendy's Company's Form 10-K for fiscal 2025 counts 5,969 US restaurants, most run by franchisees, and each one sets what it charges.
Questions people ask
What is the Wendy's Grand Slam Burger?
Four beef patties in one sandwich, also circulated as the Meat Cube. It is built by adding a patty to a Dave's Triple, and Wendy's has never sold it under either name.
How much does it cost?
$7.99 for the Dave's Triple plus an unpublished charge for the fourth patty. Nobody publishes a total. That is why the guides quoting one all differ.
What should the extra patty cost?
$1.00 to $1.20, judging by the gaps between Wendy's own listed singles, doubles and triples. That is a benchmark drawn from listed prices rather than a quote.
How many calories are in it?
The base is 1,100 for the Dave's Triple. Listed pairs put a patty at 265 to 325 calories, so the build lands near 1,365 to 1,425, none of it a company figure for this sandwich.
How much cheese goes in it?
Published accounts split between two slices and four. Since no standard exists, the sensible move is to state the count when ordering.
Will a Wendy's actually make one?
Often, off-peak, because an extra patty is a register option. A busy drive-thru is a different matter and a refusal there is normal.
Are these figures from Wendy's?
The listed prices and calorie counts are, read on 19 August 2026 from the company's own ordering site. Everything derived from them is labelled as derived on this page.
