Jack in the Box offers fresh food late at night, with kind customer service. Enjoy a Jr Jumbo Jack or order of tacos. The location on Grove is known for hot and good food, with a drive-thru employee who quickly fixes any mistakes. While the restroom needs an employee to unlock it, options like salad and chicken fajita pita are available for those with dietary restrictions. Great spot to grab a bite, especially after 3am.
