You’re driving through the West Valley, past the sprawling sports complexes and the neon glow of Glendale, and you see it—the Desert Diamond. Most people associate the casino with the frantic chime of slot machines or maybe a quick stop before a Cardinals game. But tucked inside the "White Tanks" location is something that feels like a different world entirely. Morton's The Steakhouse at Desert Diamond isn't just another casino eatery. Honestly, there's a specific kind of magic that happens when you mix a high-end Chicago legacy with the grit and glitz of a desert gaming floor.
Some folks think casino steakhouses are just overpriced pits for winners to blow their jackpots.
They aren't entirely wrong in some places. But here? It’s different.
The Location Shuffle: Glendale vs. Waddell
First, let’s clear up the confusion because Google Maps can be a real headache with this one. People search for "Morton's The Steakhouse Desert Diamond" and get hit with addresses for Glendale, Waddell, and sometimes even Avondale. Basically, this specific Morton’s is located within the Desert Diamond Casino – White Tanks, which sits at 8200 N. Sarival Ave in Waddell, AZ.
It’s about five miles from the White Tank Mountain State Park. If you’ve spent the morning hiking the Waterfall Trail, walking into this dimly lit, leather-clad sanctuary feels like a fever dream in the best way possible. You’re swapping dust and cacti for white tablecloths and "Mortinis."
What the Menu Actually Looks Like
If you’ve been to a Morton’s in Chicago or NYC, you know the drill: USDA Prime-aged beef. But the Desert Diamond location has a vibe that’s slightly more approachable while keeping that heavy-hitter quality. The Cajun Ribeye is the local legend. It’s a 16 oz cut, marinated for 48 hours, and it’s arguably the most flavorful thing on the menu.
You’ve also got the classics.
The Center-Cut Filet Mignon.
The Miso Sea Bass.
Wait, the sea bass?
Yeah. Surprisingly, the seafood here holds its own against the beef. The sea bass is buttery and flaky, served with baby bok choy. It’s the move for when you want to feel fancy but don't want to feel like you need a nap immediately after dinner.
And then there’s the Bar 12-21. The name is a nod to the date the first Morton’s opened in 1978. It’s the heart of their "Power Hour." If you aren't looking for a $100+ dinner, the bar is where the real value hides. We’re talking Petite Filet Mignon Sandwiches and those Wagyu Smash Burger Sliders that actually taste like real beef, not the frozen pucks you find at most sports bars.

The "Rose Petal" Factor: Service Nuance
One thing that genuinely surprises people is how much the staff leans into special occasions. You see it in the reviews all the time—people mention Brandi or Sydney by name. If you tell them it’s your anniversary, don't be shocked to find rose petals scattered on your table. They’ll even take a photo of you, print it out, and put it in a card. It’s a bit "old school," sure, but in a world of QR code menus and hurried service, that kind of human touch is sort of refreshing.
The Dress Code: Don't Overthink It
There is a lot of internet chatter about the dress code. The official line is "business attire or smart casual." No gym clothes. No hoodies.
But look, this is a casino in the Arizona desert.
You’ll see guys in $2,000 suits sitting next to a guy in a nice polo and clean jeans who just walked off the casino floor. As long as you don't look like you just rolled out of bed or came straight from the pool, you’re fine. It’s "Desert Fancy," which basically means "wear a collar and you're good."
Is it actually worth the price?
Let’s be real. A dinner here for two, with a couple of cocktails and a side of that Lobster Macaroni & Cheese (which is essentially a meal in itself), is going to run you $200 to $300.

Is it worth it?
If you’re comparing it to a local diner, obviously not. But if you’re looking for a curated experience where the steak is consistently perfect and the wine list is a 2025 Wine Spectator Award winner, then yeah, it hits the mark. It’s about the atmosphere. It’s the fact that you can have a world-class meal and then, five minutes later, be back at a blackjack table.
Navigating the Logistics
The hours are a bit tighter than the casino itself.
- Sunday – Thursday: 3:30 PM – 9:00 PM
- Friday – Saturday: 3:30 PM – 10:00 PM
The "Power Hour" (their version of Happy Hour) usually runs from 3:30 PM to 6:00 PM on weekdays. This is the absolute best time to go if you want the Morton’s experience without the Morton’s mortgage payment. You can grab those famous Onion Rings—which are basically the size of doughnuts—and a drink for a fraction of the dinner price.
Actionable Takeaways for Your Visit
- Book the Booths: When you make a reservation on OpenTable, specifically request a booth in the main dining room. The chairs at the freestanding tables can be a bit stiff, and the booths offer that classic, secluded steakhouse feel.
- The Secret Bread: The onion bread is legendary. It’s warm, it’s soft, and it’s addictive. If they don't bring it out immediately, ask. It's part of the ritual.
- Skip the "Medium": Morton's high-heat broilers are intense. If you like your steak Medium, consider ordering it Medium-Rare. The carry-over cooking on those thick cuts is real.
- The Souvenir Photo: If you're celebrating something, let the host know. They will take a photo and frame it for you for free. It’s a cheesy but great memento.
- Check the "Bubbles & Bites": They often run limited-time specials like a three-course meal for around $69. It’s the most cost-effective way to try the signature items.
The next time you're at the Desert Diamond, don't just settle for the food court. Even if you're just there for a drink at Bar 12-21, Morton’s provides a level of polish that’s rare in the West Valley. It’s a slice of Chicago tradition sitting right on the edge of the White Tank Mountains.
To ensure you get the best experience, head over to the official Morton’s website or the Desert Diamond "White Tanks" dining page to check for seasonal menu changes or special "A Cut Above" event dates. Making a reservation at least 48 hours in advance is highly recommended, especially on weekends when the casino is packed.
