Jack in the Box offers fresh food late at night, with kind customer service. This location on Grove is known for hot and good food, making it a great spot to grab a bite, especially after 3am. Customers can enjoy a Jr Jumbo Jack, an Ultimate Breakfast Sandwich, or an order of tacos. The drive-thru employee is quick to fix any mistakes, and most often, the service is fast and professional. However, it can depend on who is at the window, as experiences can vary greatly. While the restroom needs an employee to unlock it, options like salad and chicken fajita pita are available for those with dietary restrictions. Some customers have noted that prices have increased, which can affect perceived food quality. Overall, Jack in the Box remains a popular choice for late-night cravings, especially for items like the Strawberry milkshake and Chili fries.
