Unwritten Rules To Know Before Visiting Whataburger

There are seemingly endless American burger chains out there, all offering slightly different versions of essentially the same things. However, once you start looking at slightly smaller, more regional chains, you can more often see some unexpected burger styles and flavors that make an average fast food run a bit more interesting. That's certainly true when it comes to Whataburger. This chain originated in Corpus Christi, Texas, so it undoubtedly has a Texas flavor to it, but these days, you can find Whataburger locations scattered across the Southeast and parts of the Southwest.

Because this chain hasn't yet reached every corner of the country, there's a lot you might not know about it. While you can obviously just walk in and order whatever you want without knowing much about what Whataburger has to offer, having a sense of what to expect can make your first trip tastier. That's why we're covering these unwritten rules to know before visiting Whataburger. These may not be hard-and-fast rules, but following them will yield a more delicious dining experience and may help you avoid some common ordering pitfalls. Let's take a closer look at the rules you should be following the first time you visit before reading up on the best Whataburger hacks to try.

If there's one thing you should know about Whataburger, it's that the burger joint is really focused on mustard. At a lot of fast food burger places, mustard functions as an afterthought. It might be included on a specific burger, but it's far from the star of the show. On many other fast food hamburgers, you won't find any mustard at all, so you'd have to request it specifically if you wanted that special, tangy condiment to even appear on your sandwich. But at Whataburger, it functions as a base condiment — it's automatically added to every burger. And if you love mustard just as much as I do, then you can understand why so many people adore this fast food spot. You can request it be left off, but there's probably going to be a lot of mustard on your burger if you don't specify you don't want it.

But the mustard Whataburger uses isn't the plain old yellow variety you have hanging out in your fridge. Rather, the brand has its very own signature mustard. This is a yellow mustard (as you'd expect on a burger), but I've noticed that it has a slight sweetness that really makes your burger pop. I love how boldly vinegar-forward it is, which plays well with the fattiness of the burger patty.

Whataburger is a Texas brand, so it shouldn't come as any surprise that the burgers are bigger than average. When you order a burger from McDonald's, for example, the burger is about 4 inches wide from side to side. A burger patty's thickness factors into how much meat you get, but the diameter determines how large the burger is overall. At Whataburger, though, a standard burger is 5 inches in diameter. That may not sound like much of a difference, but in my experience, that extra inch adds quite a bit of food to the sandwich overall and makes for a significantly more filling meal than you'd get at other fast food burger spots. Even though I can easily finish most fast food burgers, I struggle to finish an entire Whataburger.

That's not a bad thing if you're feeling particularly hungry, but not everyone wants a burger that's offered at such an intimidating size. If you're looking for something a little lighter, opt for a Whataburger Jr. instead. These are 4 inches in diameter, so they're more on par with a standard fast food burger. And when you see "junior," just keep in mind that this basically just means "normal" at this chain.

Many people think of their favorite fast food restaurants and fast food breakfast very differently. After all, just because a spot does a burger well doesn't necessarily mean it will deliver on the breakfast front. But at Whataburger, it pays to check out the breakfast menu. There are a couple of reasons for this. First of all, breakfast is available from 11 p.m. to 11 a.m., which makes Whataburger one of the few fast food restaurants where you can grab breakfast for a late-night meal. But more importantly, the chain offers up some seriously delicious options for this meal.

My personal favorite is the Honey Butter Chicken Biscuit. Sure, you can find chicken biscuits at a wide variety of chicken fast food chains, but this one is so special because of that honey butter addition. It's rich and creamy, but it has that gooey sweetness you'd also expect from a really honey-rich honey butter. Plus, I've found they're pretty generous with the chicken patty size here. Order it with the jalapeño cheddar biscuit for a touch of sweet heat that makes this breakfast irresistible. As a spicy-sweet lover, I found it one of the most delicious breakfast flavor combos I've ever tried. Make sure to try some of the other breakfast options as well. From breakfast burgers to biscuits and gravy, this chain has you covered on the breakfast front.

Whataburger is all about the mustard. It's the chain's signature sauce and part of what makes the burgers taste so mouthwatering. But that doesn't mean mustard is the be-all, end-all when it comes to condiments. There are plenty of other sauces you can add to your burger (and enjoy on the side as a dip for your fries), from mayonnaise to ranch dressing to Buffalo sauce. For those who like to keep things classic, though, one of the most common additions is likely the brand's fancy ketchup. For the spice lovers out there, the spicy take on this condiment is Whataburger's spicy ketchup, which might be the best way to add both sweetness and heat to your burger.

So, what's so great about this ketchup? First of all, it seems to be higher quality than most basic ketchup brands out there. I find it to be a lot thicker than normal ketchup, with a much bolder fresh tomato flavor as well. Additionally, I think that the sweetness here is a bit more balanced than you find with other ketchup. The real appeal, of course, is that hint of spice. It has a vegetal note, with a distinctive jalapeño kick that's bold enough to win over the spicy lovers but not so spicy that it'll make your burger difficult to stomach. Just be sure to request it separately.

It's true that some fast food restaurants allow you to customize your orders, but I think Whataburger offers more options than many other restaurants out there. You'll find tons of burger add-ons on the menu, from grilled onions to bacon slices to avocado, in addition to the different sauce options. But one of the things I like most about Whataburger is that you can swap out your standard bun for Texas toast instead. This might just be the best way to lean into the whole Texas thing that Whataburger has going on.

Now, using Texas toast for your burger makes this a very different type of sandwich. Admittedly, the Texas toast is kind of oily. This gives the exterior of the bread a delicious crispness to it that I love — it makes the already rich burger taste even more decadent. However, it makes eating your burger a bit messier. Ultimately, though, I think that messiness is worth it, and since you can't get your burger on Texas toast everywhere, it should be a rule that you try it when you eat at Whataburger.

Once upon a time, it wasn't uncommon for fast food restaurants, diners, and other food establishments to be open 24 hours a day, seven days a week. But after the COVID-19 pandemic, it seems many of those restaurants now close at night, leaving customers with fewer options for late-night dining. But Whataburger isn't one of those restaurants. The chain started out as a restaurant that was always open back in the 1950s, and it has decided to stay true to that policy. Even now, most Whataburger locations are open 24/7, so you can snag yourself a burger at basically any time of day.

Of course, this may not be true for every single Whataburger location, so you should check that your local spot is open before you head over there super late at night. But as long as it is open, it should be a rule not to limit your Whataburger runs to normal working hours for most fast food joints — whenever the craving hits you, Whataburger has you covered, no matter what time it is.
