Whataburger Hours: Open & Close Times, Breakfast & Lunch Hours by Location
Whataburger is the rare chain that is built around being open all night: its own announcement says all locations are open 24/7, 364 days a year, except those in venues with limited hours. Our reading of 146 restaurant pages in Houston, Dallas, San Antonio and Phoenix on October 13, 2026 confirms the drive-thru is open 24 hours at nearly all of them, while the dining room is 24 hours at roughly half and closes at midnight or earlier at the rest. The breakfast menu runs from 11 PM to 11 AM.
Why Whataburger Hours Vary by Restaurant
Because Whataburger operates through independently managed franchises and diverse retail footprints (such as standalone drive-thrus, shopping mall units, and travel plazas), there is no single national schedule. Operating windows, breakfast cutoffs, and lobby access times differ noticeably between locations.
Based on Whataburger Restaurants LLC official directory and corporate operating statements.

Whataburger Hours: Are They Open 24 Hours?
Yes, with a caveat that matters. Every Whataburger restaurant page on locations.whataburger.com has separate dine-in and drive-thru hours, and the two often differ.
| City | Pages read | Drive-thru open 24 hours | Dining room open 24 hours |
|---|---|---|---|
| Houston, TX | 56 | 54 | 14 |
| Dallas, TX | 21 | 18 | 9 |
| San Antonio, TX | 59 | 52 | 47 |
| Phoenix, AZ | 10 | 10 | 9 |
The drive-thru is the dependable part: 134 of the 146 pages list the drive-thru as open 24 hours every day. The dining room is less certain. San Antonio, the chain's home city, is the most generous, with 47 of 59 dining rooms open all hours, while only 14 of 56 Houston dining rooms are. If you want to sit inside at 3:00 AM, look at the dine-in line, not the drive-thru line.
Whataburger Dining Room Hours: When Does the Lobby Close?
| Dining room schedule | Houston | Dallas | San Antonio |
|---|---|---|---|
| Open 24 hours | 14 of 56 | 9 of 21 | 47 of 59 |
| 6:00 AM – midnight every day | 12 | 7 | 5 |
| 6:00 AM – midnight; to 3:00 AM Fri and Sat | 9 | not in the top groups | not in the top groups |
| 6:00 AM – 10:00 PM every day | 6 | not in the top groups | not in the top groups |
| 6:00 AM – 1:00 AM every day | 5 | not in the top groups | not in the top groups |
In every non-24-hour group we read, the dining room opened at 6:00 AM, and the drive-thru stayed open all night. So the practical rule is simple: use the drive-thru after the lobby closes and expect a 6:00 AM lobby opening at the restaurants that do close. Nine Houston restaurants closed the lobby at midnight on most nights but kept it open until 3:00 AM on Friday and Saturday.
Whataburger Breakfast Hours: 11 PM to 11 AM
Whataburger's breakfast window is unusual because it starts at night. A Houston restaurant menu on whataburger.com lists a Breakfast (11pm-11am) category, and company stories about the Breakfast Burger describe it as available only during breakfast hours from 11 p.m. to 11 a.m. That makes the overnight shift the breakfast shift: a customer at the drive-thru at 2:00 AM is already inside the breakfast window.
Whataburger Hours on Friday, Saturday and Sunday
For the drive-thru, there is no weekend difference: it runs 24 hours every day at the restaurants we read. For the dining room, Friday and Saturday are the extension nights. At nine Houston restaurants the lobby closed at midnight Sunday through Thursday but ran to 3:00 AM on Friday and Saturday. Sunday follows the weekday schedule.
Late-Night Whataburger: Lobby or Drive-Thru?
At night the choice depends on what you need. Of the 146 pages we read, only 79 listed a dining room open around the clock, which leaves 67 restaurants where the lobby locks at some point, usually midnight, 1:00 AM or 10:00 PM. The drive-thru, by contrast, stayed open all day and all night at 134 of the 146. That is why the same restaurant can read Open 24 hours on one line of its page and 6:00 AM to midnight on the next.
- Need a seat or a restroom after midnight: filter for a restaurant whose Dine-In line says 24 hours; San Antonio has the highest share.
- Just need food: any restaurant whose Drive-Thru line says 24 hours will do, which is nearly all of them.
- Arriving on foot: confirm the Dine-In line, because the drive-thru hours describe the lane, not the lobby.
Is Whataburger Open Now? Checking Your Restaurant
- Open locations.whataburger.com, choose your state and city, then pick the restaurant.
- Compare the Dine-In and Drive-Thru lines; each page has its own hours tables, plus curbside and delivery hours.
- Look for the note Holiday hours might differ at the bottom of the hours section.
- If a restaurant lists limited hours, it is probably in a venue such as an airport or campus, which the company says are the exception to 24/7.
Houston alone has 56 restaurant pages in the directory, so there is usually a 24-hour option within a short drive. In San Antonio, with 59 pages, most dining rooms are open all night as well.
