You’re driving down Jericho Turnpike, probably stuck in that weird pocket of traffic near the courthouse, and you see it. The Rex. It looks like a classic burger joint from the outside, but the Rex Mineola menu is actually a weirdly specific ecosystem of burgers, fries, and shakes that people in Nassau County treat like a religion. Honestly, if you live on Long Island, you've probably had someone tell you that this place is the "Shake Shack killer," which is a bold claim, but it's one they've been backing up for years.
The thing is, first-timers usually mess up their order. They go in and just ask for a "burger," not realizing that the way you customize your meal here is basically an art form. It's not just about beef and buns. It's about the specific ratio of that "Rex Sauce" to the potato roll and how the grilled onions interact with the grease.
Why the Rex Mineola menu is different from your average burger spot
Most fast-casual places try to do everything. They have salads, they have wraps, they have twenty different types of appetizers. The Rex doesn't care about that. The Rex Mineola menu is stripped down. It's focused. You have burgers, you have hot dogs, you have hand-cut fries, and you have milkshakes. That’s pretty much the whole game.
But within those narrow lanes, there's a ton of depth. Take the beef, for example. They use a proprietary blend that’s never frozen. You can taste the difference immediately. It’s got that "smash burger" crust but stays juicy in the middle. If you've ever had a burger at a high-end steakhouse and then had one at a drive-thru, you know that middle ground is hard to hit. The Rex hits it every single time.
The menu is built on a "Build Your Own" philosophy. You start with a Single, Double, or Triple (if you're feeling particularly brave or very hungry). Then you pick your toppings. Most are free. Lettuce, tomato, raw onions, pickles—the standard kit. But then you get into the stuff that actually makes it The Rex. Grilled onions. Sautéed mushrooms. Jalapeños. And, of course, the Rex Sauce.
Breaking down the Rex Sauce mystery
People talk about the sauce like it’s some secret government formula. It’s not. It’s a mayo-based condiment with some tang, some sweetness, and a little bit of a kick. But on the Rex Mineola menu, it acts as the glue. Without the sauce, you just have a really good burger. With the sauce, you have a "Rex Burger."
It’s worth noting that the sauce isn't just for the burgers. Smart regulars know to ask for a side of it for the fries. The fries here are hand-cut and double-fried, which means they have that specific Belgian-style crunch on the outside while remaining fluffy inside. Dipping those into the Rex Sauce is basically a requirement for the full experience.

Navigating the burger tiers
If you’re looking at the Rex Mineola menu for the first time, don't get overwhelmed by the options. Most people gravitate toward the "Double Rex." It’s two patties, cheese, and your choice of toppings. It’s the gold standard.
- The Single: This is actually a decent amount of food. Because the patties aren't paper-thin like at some other chains, a single is a legitimate meal. It’s perfect if you’re also planning on crushing a large order of fries or a shake.
- The Double: The most popular choice. It gives you the perfect meat-to-bun ratio. When you add the cheese, it melts between the two patties and creates this beautiful, gooey situation that holds everything together.
- The Triple: This is a lot. Honestly, it’s a bit of a project. You need multiple napkins. You might need a nap afterward. But if you’re a "meat-over-everything" person, this is your play.
- The Veggie Burger: Surprisingly, they don't phone this in. It's a solid option for people who aren't into beef but still want that greasy-spoon experience.
The buns are another thing. They use Martin’s Potato Rolls. It’s the industry standard for a reason. They’re soft, they’re slightly sweet, and they don't fall apart when the burger grease starts to soak in. A burger is only as good as its bun, and the Rex Mineola menu respects that rule.
Beyond the beef: Dogs and Chickens
While the burgers get all the press, the hot dogs on the Rex Mineola menu are underrated. They use Sabrett’s—the classic New York frank—but they split them and griddle them. This gives the casing a snap that you just don't get from boiling or standard grilling. If you're not in the mood for a burger, a "Rex Dog" with some spicy mustard and onions is a sleeper hit.
Then there's the chicken. The Rex has a crispy chicken sandwich that actually gives the big national chains a run for their money. It’s a breast fillet, breaded and fried to order. It’s crunchy, it’s salty, and it actually tastes like chicken rather than a processed sponge. You can dress it up with the same toppings as the burgers, but honestly, just some pickles and a little Rex Sauce is all it needs.
Let's talk about those shakes
You cannot mention the Rex Mineola menu without talking about the milkshakes. They are thick. Like, "break your straw" thick. They use real ice cream, and you can tell.
- Vanilla and Chocolate: The classics. Done right. No artificial aftertaste.
- Black and White: A NY staple. Vanilla ice cream with chocolate syrup. It’s the best of both worlds.
- Strawberry: Made with real fruit. It’s refreshing, or at least as refreshing as a 600-calorie dairy bomb can be.
- Specialty Flavors: They often have seasonal or rotating shakes like Cookies and Cream or Salted Caramel.
If you're going all out, the move is to get a Double Rex, a side of fries, and a shake. It’s the "Rex Trifecta." It’s not a light lunch. It’s an event.
The "secret" to ordering like a local
When you walk into The Rex, it's usually buzzing. The kitchen is open, you can see the grill, and the smell of searing beef is everywhere. To order like you've been there a hundred times, keep it simple but specific.
Don't just say "everything on it." The Rex Mineola menu toppings can get messy if you overdo it. The "local" way is usually cheese, grilled onions, pickles, and Rex Sauce. Maybe some jalapeños if you want some heat. That combination highlights the quality of the beef without burying it under a mountain of lettuce.

Also, pay attention to the fries. They offer "Rex Fries" which come topped with cheese sauce and grilled onions. It's their version of animal-style fries, and they're incredible. But a word of warning: they are heavy. If you're getting a burger and a shake, you might want to stick to the regular fries. Or don't. Live your life.
The Mineola vibe
Mineola is a weird place. It's the county seat, so you have lawyers in suits, people going to the DMV, and high school kids all converging in one spot. The Rex reflects that. It's one of the few places where you'll see a judge sitting at a counter next to a construction worker, both of them covered in Rex Sauce.
The atmosphere is "modern diner." It's clean, industrial, and fast. But unlike a lot of fast-food joints, there's a level of care here. You can tell the staff actually gives a damn about the temperature of the oil and the sear on the meat. That's why people keep coming back.
Is it worth the hype?
In a world of $20 "boutique" burgers, the Rex Mineola menu stays relatively grounded. It’s not the cheapest meal in town, but the value is there because the quality is so much higher than what you'd get at a drive-thru.
There are critics, of course. Some people think the fries are too greasy (they are hand-cut, so they hold more oil than frozen sticks). Others think the menu is too small. But that’s the point. The Rex does a few things perfectly rather than doing twenty things "okay."
If you compare it to other local icons like All American in Massapequa, The Rex feels more modern. It’s the evolution of the Long Island burger stand. It’s got the soul of a 1950s shop with the ingredients of a 2026 gastropub.
Actionable steps for your first visit
If you're planning to check out the Rex Mineola menu this week, here’s how to do it right:
- Check the timing: If you go at 12:30 PM on a weekday, you're going to wait. It's right near the courts and the hospital. Aim for 11:45 AM or 2:00 PM if you want to avoid the heaviest crush.
- The App is your friend: They have an online ordering system. Use it. You can walk in, grab your bag, and bypass the line of hungry people looking at the menu board.
- Parking is tricky: The lot is small. Don't be afraid to park a block away and walk. It’ll help you justify the milkshake you’re about to drink.
- Ask for extra napkins: You will need them. More than you think. The burgers are juicy, and the sauce is generous.
- Try the grilled onions: Even if you think you don't like onions, try them here. They cook them down until they're sweet and caramelized, and they basically melt into the cheese.
The Rex Mineola menu isn't trying to reinvent the wheel. It's just trying to make the best possible version of a classic American meal. Whether you're a lifelong Long Islander or just passing through Nassau County, it’s a spot that earns its reputation one burger at a time. Grab a seat at the counter, watch the grill for a minute, and enjoy one of the best meals you can get for under twenty bucks.
