In-N-Out and Whataburger fans do not argue like McDonald's and Burger King customers. They argue like rival faiths. For decades geography kept the peace: In-N-Out stayed west, Whataburger stayed in Texas and the South, and never the Double-Double and the Patty Melt had to share a parking lot.
Update, Aug 27: our latest data refresh already grew the map. It's 244 In-N-Out exits and 655 Whataburger exits now, and the shared count jumped from 14 to 19. Told you this one was moving fast.
That peace is ending, and our database can show you exactly where.
Twelve are in Texas. The other two are in Nashville, Tennessee — In-N-Out's brand-new eastern beachhead, planted directly in Whataburger territory.
| Metro | The front line |
|---|---|
| Dallas–Fort Worth (7) | I-20 Exits 467A, 467B, 468 · I-30 Exit 68 (Rockwall) · I-35E Exit 414 · I-35W Exit 61 · I-820 Exit 10A |
| San Antonio (3) | I-35 Exit 166A · I-410 Exits 26B and 27 |
| Waco (1) | I-35 Exit 335A — across from Baylor, the college-town flashpoint |
| San Marcos (1) | I-35 Exit 190B |
| Nashville (2) | I-24 Exits 60 and 60B (Antioch) — the eastern front |
Notice what's missing: California. Whataburger has never crossed into In-N-Out's homeland, so every single contested exit sits in Whataburger country. This is a one-directional invasion, and I-35 is its main axis: six of the fourteen exits are on one highway.
The two Tennessee exits are the tell. In-N-Out's eastward expansion put its first Tennessee locations directly on top of exits Whataburger had already claimed, which means the overlap map is about to grow for the first time in decades. The burger cold war finally has a front that moves. We'll re-run this query as it does.
