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, 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.

It’s not always you fun into patient and cheerful employees at a fast food joint but that’s this place… at least when we were there on Sunday. I like those jalapeno poppers and the egg roll was a decent buy. Service was fast, like, really fast, and the milkshake desserts just as good as the meal. 10/10 would eat here again if I’m in downtown San Marcos and have a hankering for Jack’s.

5 large combos for $75 for burgers!!!! We don’t have a Jack in the Box near us, this one in San Marcos is 1/2 an hour away, we crave Jack in the Box every once in a while and it’s a treat for us right now because of the distance, but I was shocked to know that 5 large combos are going for that price! I will double think it when I want to treat my family, I’m pretty sure I can find more options for that price tag.

The food was subpar for a jack in the box, employees did not use gloves when handling food at times. The ceiling is really gross (weird stains everywhere) and the soda machine is often out of many flavors/syrups. If you’re not a fan of being stuck on the toilet, steer clear.

Food is always fresh. My husband always gets their soft/crunchy tacos and they’re always so greasy but he likes them so I guess its cool. Great drive thru service

The chicken nuggets are kinda like McDonald’s but slightly better. We ordered the midnight munchie meal with is definitely a bang for your buck you get a drink, 2 tacos, curly and regular fries with 4 different sandwich options to select from. Also ordered a 10 pc nuggets with the loaded fries. Not a fast food place i’d go again. Also not a big fan of fast food. Also not the nicest workers definitely did not enjoy their job, but understandable i wouldn’t either working at Jack in the Box.

I had an unfortunate experience at this establishment, where the customer service was extremely disappointing. One staff member, a woman with distinctive ear gauges, seemed to disregard my presence, despite my being the sole customer in line. Similarly, another employee, a thin man with tattoos, also failed to acknowledge me. The atmosphere and overall cleanliness of the place left much to be desired. I would urge the management to address these issues and provide better service to their patrons.

This is genuinely the best Jack-in-the-Box in San Marcos. The one off of wonder world, is awful, it never gets anything right, and the food is subpar. This Jack-in-the-Box always has superior service, always gets my food to me, hot and fresh, and there are always people smiling here.
