Looking for food in Orange County at 2 a.m., 4 a.m. or any other hour? This guide focuses on restaurants that are currently open 24 hours a day, plus a smaller section for useful late-night restaurants that are not always open around the clock.
Restaurant hours can change, and some locations keep the drive-thru open later than the dining room. Always check the restaurant’s current hours before making a late-night trip.

24-Hour Fast Food & Drive-Thrus
Fast-food hours vary widely by location. In some cases, only the drive-thru is open overnight while the dining room closes earlier. For chains, the most reliable approach is to use the official locator rather than a static address list.

Some Orange County Carl’s Jr. locations operate 24 hours or keep extended drive-thru hours. Use the official Carl’s Jr. locator to confirm the current schedule.
Del Taco
Some Orange County Del Taco locations operate 24 hours, but the schedule is location-specific. Use the Del Taco location finder to confirm current hours. For local history, see our guide to the Original Del Taco.

Late-Night Restaurants That Aren’t Always Open 24 Hours

City: Orange
Food: Breakfast, burgers, tacos and diner food

Harbor House Cafe
Locations: Sunset Beach and Dana Point
Food: Diner-style breakfast, lunch and dinner
Best for: Classic late-night diner atmosphere
Harbor House has long been associated with 24-hour service, but its own website currently tells guests to call for store hours. Because third-party listings and the official site do not present the schedule consistently, verify the current hours directly before making a late-night trip.
