SOURDOUGH GRILLED CHICKEN CLUB The password to this club? “Grilled all-white meat chicken topped with bacon, Swiss-style cheese, lettuce, tomato and real mayonnaise on toasty sourdough bread.” That’s right, it’s quite a mouthful. Don’t think that wasn’t on purpose.
CRISPY CHICKEN STRIPS The name says it all. And your mouth says, “stop talking about the name and start dipping these all-white meat chicken strips in Buttermilk Ranch and putting them in me.”

TACOS, FRIES & SIDES
SEASONED CURLY FRIES These Curly Fries are seasoned, alright. Seasoned veterans. They’ve been around the block—gathering deliciousness and flavor from all over. So, they know how to make your mouth water. And your tastebuds do their secret handshake.
FRENCH FRIES Most French fries in the world don’t deserve their own description, but Jack’s do. Because these lightly salted, real potatoes are fried to crispy perfection and served hot and salty. They’re just that tasty.
ONION RINGS True love is not an engagement ring. It’s an onion ring—panko breaded and fried to jaw-dropping perfection. But using an onion ring as an engagement ring? The judge will allow it. Just kidding. There’s not a judge for this type thing. Do whatever …
EGG ROLLS It’s what’s on the inside that counts. That goes for you, sure. But it definitely goes for these crispy egg rolls—filled with diced pork, cabbage, celery, carrots, onions, and spices. But don’t forget the outside, where there’s sweet and sour dipp…
STUFFED JALAPEÑOS Where most see jalapeños, Jack sees opportunity. To bread ‘em and fill ‘em with melted cheeses. Yes, plural. And, if things get too hot, there’s tasty buttermilk ranch dipping sauce to cool down. Mmhmm. Jack’s got your back. And your stomach.
TWO TACOS Sure, one is nice. But do you know what’s better? Two. Two crunchy tacos with American cheese, shredded lettuce, and taco sauce. Because two will always be greater than one. Who knew math could be so mouth-watering? Oh, right. We did.
BREAKFAST
JUMBO BREAKFAST PLATTER Breakfast doesn’t come shaped in a bar. Or in a fancy juice. Real breakfast is served on a platter—a jumbo platter with tasty scrambled eggs, hash browns, eight mini pancakes, and your choice of country grilled sausage or three slices of bacon. Ch…
SUPREME CROISSANT This breakfast croissant is more than good. Heck, it’s more than great. This flaky piece of heaven is supreme. Because it’s got grilled bacon, ham, a freshly cracked egg, and American cheese. And when you take a bite, you’re supreme, too. Those ar…
SAUSAGE CROISSANT When Jack put sausage, a freshly cracked egg and American cheese on a buttery croissant, it earned the coveted title: “the sausage, freshly cracked egg and American cheese buttery croissant.” But that wouldn’t fit on the menu. Or anywhere. Hence, …

MEAT LOVERS BREAKFAST BURRITO Favorite fruit? Meat. Favorite veggie? Meat. Favorite burrito? This one. It’s got bacon, sausage, and ham—plus, scrambled eggs, pepper jack and cheddar cheese. And it’s all wrapped in a warm flour tortilla with a side of fire roasted salsa. Now th…

GRILLED BREAKFAST SANDWICH You can pinch yourself all you want, but this isn’t a dream. This is the Grilled Breakfast Sandwich. With two freshly cracked eggs, two slices of ham, two strips of bacon and two slices of melting American cheese all on grilled artisan bread. Seri…
SAUSAGE, EGG & CHEESE BISCUIT Four words: Sausage. Egg. Cheese. Biscuit. Yeah, finally, you’ll want to eat your words. Because this buttermilk biscuit is topped with a freshly cracked egg, American cheese and sausage. Scratch that, it’s one word: Incredible.
BACON, EGG & CHEESE BISCUIT Say cheese. Nice. Now say bacon. Double nice. Now say buttermilk biscuit topped with a freshly cracked egg, American cheese, and bacon. You’re officially fluent in deliciousness. Go ahead, put it on your resume.
SAUSAGE BREAKFAST JACK® The name speaks for itself. This is breakfast, Jack-style. Think sausage, a freshly cracked egg, and American cheese—all on a bun. Now, try to think of something else. That’s right. You can’t.
BREAKFAST JACK® The name speaks for itself. This is breakfast, Jack-style. Think ham, a freshly cracked egg, and American cheese—all on a bun. Now, try to think of something else. That’s right. You can’t.
HASH BROWNS No breakfast is complete without hash browns that are perfectly crispy on the outside and oh-so-amazing on the inside. And if somebody says otherwise, they’re lying.
MINI PANCAKES It doesn’t get any better than warm and fluffy pancakes. Unless you make them bite-sized. And make eight of them—with a side of pancake syrup. Which is exactly what Jack did. Right before he high-fived himself.
LATE NIGHT
SRIRACHA CURLY FRY BURGER MUNCHIE MEAL We’ve all thought it, but only Jack did it. Curly fries on a cheeseburger. That’s right. This burger got itself a perm. And, unlike the one your friend got in high school, it looks hot. And not just because of the Creamy Sriracha. But it does help…
SPICY NACHO CHICKEN SANDWICH MUNCHIE MEAL This is not an ordinary meal. Because this is our new 100% all white meat chicken fillet, that is bigger, crispier and better than ever, topped with onion rings, jalapeños, and nacho cheese sauce on toasted sourdough. And two regular tacos. And ha…
STACKED GRILLED CHEESE BURGER MUNCHIE MEAL When you see a sourdough grilled cheese standing on the shoulders of a cheeseburger, your jaw will drop. And then pick itself up. Then drop again. Because yeah, you’re already chewing. Along with two regular tasty tacos, halfsie fries, and a small…
CHICK-N-TATER MELT MUNCHIE MEAL Everybody loves the O.G. Chick-n-Tater Melt with crispy chicken, a hash brown, ooey-gooey cheese, bacon, and ranch, all on a croissant bun.
SHAKES & DESSERTS
OREO® COOKIE ICE CREAM SHAKE Sorry, Milk, but OREO® has a new best friend—old-fashioned thick shakes. Made with real vanilla ice cream, OREO® cookie pieces, topped with whipped cream and a maraschino cherry. Seriously, Milk. Move on. Sign up for online dating or something.
CHOCOLATE ICE CREAM SHAKE Remember those old-fashioned thick shakes the cool kids drank on the hoods of their cars in those classic movies? So does Jack. That’s why he made this chocolatey treat with real vanilla ice cream, chocolate sauce, topped with whipped cream and a …
VANILLA ICE CREAM SHAKE An old-fashioned thick shake made with real vanilla ice cream, whipped cream and a maraschino cherry will never go out of fashion. And if it did, who’d want to live in that world anyway? Nobody is the correct answer. That’s right. Nobody.
STRAWBERRY ICE CREAM SHAKE Every berry had a chance, but—in the end—only strawberry deserved to be in Jack’s old-fashioned thick shakes. Made with real vanilla ice cream, strawberry syrup, topped with whipped cream and a maraschino cherry. Boysenberry is still bitter it did…
MINI CHURROS Each churro is like a bite-sized trip to the carnival. Except with even more cinnamon and pure cane sugar. And no waiting in line for the Ferris wheel.
CHOCOLATE OVERLOAD™ CAKE If you’re looking for vanilla, you’ve made a wrong turn. Because this is a rich chocolate cake made with cocoa, bittersweet chocolate chips and then drizzled with chocolate buttercream icing. That’s some chocolatey chocolate chocolateness. That’s …
NY STYLE CHEESECAKE The Big Apple has relocated to your mouth. And it’s not literally an apple. It’s a light and creamy cheesecake with a graham cracker crust. That’s way tastier than some over-rated piece of fruit.
DRINKS
COCA COLA FREESTYLE
ORIGINAL ICED COFFEE The chilled Premium Roast Coffee with sweetened cream will leave you refreshed and your sweet tooth saying, “more, more, more!”
CARAMEL ICED COFFEE Is it pronounced Car-A-mel? Car-mel? Car-UH-mel? Actually, who cares? No matter how you say it, you’ll want to drink it. A chilled blend of Premium Roast Coffee, caramel, and sweetened cream. Your taste buds just whispered, “giddy up.”
MOCHA ICED COFFEE Jack didn’t reinvent the wheel. He would’ve, but he was too busy making the Mocha Iced Coffee—a refreshing blend of chilled Premium Roast Coffee, mocha, and sweetened cream. Everybody agrees that was a better use of time.
PREMIUM ROAST COFFEE This premium roast coffee is premium for a reason. And that reason is 100% Arabica beans. Not 99%. And not 99.9%. And definitely not 101%. Because that’s a mathematical impossibility.
FRESH BREWED ICE TEA An authentic, high quality, fresh brewed iced tea that is perfectly balanced to deliver a smooth and refreshing taste.

I will say the crew was nice and the food was good quality but if the order is wrong it doesnt matter. I ordered a value chicken sandwich and 2 tacos. They gave me 1 taco. Such an easy order, and I don’t think they even sell individual tacos. Probably an oops but still annoying

You should be able to leave zero stars! This place is such a joke. Just close already. Worst slow food service I’ve experienced. Complete incompetence. I don’t think employees have any training or guidelines to follow at all. Owner should really look at who is running this store because it’s appalling. Gross

I stopped on the way home to get gas at Phillips 66 and also got dinner at Jack in the Box. The service was really good and they got our order just right. The food was very tasty and prepared well. I would definitely go back to this location.

Nicest crew ever! The 2 guys at the counter this morning were super pleasant and helpful, since I’d never been to a jack in the box before, ever. Even the custodian was smiley! A good experience all around. Here’s a helpful hint: they told me to put grape jelly on my hash browns which sounded terrible but was really good!

I stopped in after craving a loaded breakfast sandwich for probably 2 months. It was perfect and satisified the craving. I know this location can be hit or miss but the crew at around 5pm did a great job.

Show up at 9:30 and I’m told they are only accepting DoorDash and mobile orders, no worry. Got to place a mobile order and see that the store reports it’s closed, okay. Pull back up to window and the employee says they are only accepting mobile orders. Explain that the app says they are closed. Employee says okay let me check and never returns after 10 minutes. Horrible management.

Rick Wallis

Lol, went by today, and they are out of chicken, tacos, poppers, and about 10 other things, posted to the drive through menu. Who runs that location? They should be fired. Every other day they are out of half their menu. Hire me to run that franchise, whoever is doing it now has no clue.

Haley Davis

I’m gonna give a 5 star review tonight because the ladies gave my boyfriend and I the best service!! We pulled up, and they took our order right away. Then we pulled up to the window and got great energy. Our food was hot when we arrived home! Thanks ladies.

Mark Lemen

How is this place still open? The employees are lazy and don’t serve you fresh food. My last 3 or 4 visits have been disastrous. Save your money and just go to the Wendy’s across the street.
