The year 2016 opened a deep rift between two factions already prone to distrust each other. A battle for supremacy raged, insults flew and a long-simmering culture war reignited.

This rift had nothing to do with politics. It had everything to do with breakfast tacos, and whether Austin or San Antonio could properly claim credit for their creation.

And in this case, the leaders of the warring Texas taco tribes — Austin Mayor Steve Adler and San Antonio Mayor Ivy Taylor — came together to pledge peace. The “I-35 Accords,” named for the interstate that connects two of the fastest-growing metropolises in America (they are about 80 miles apart), formally declared each city’s tacos equally delicious.

“There is more that unites our tacos than divides them,” Adler said in March 2016 at the signing ceremony. “Let us break our fast with the tortilla of hope and the egg of peace.”

Tell someone you’re going to Austin and they will recommend barbecue joints such as Lambert’s and Franklin, where the lines can stretch out the door for hours.

Instead of baking in the Texas heat while waiting for barbecue, I decided to make a careful study of Austin’s taco scene. What, I wondered, would the evolution of such a simple meal say about a city influenced by Mexican and American cultures?

Locals will tell you that the taco, in all its myriad forms, perfectly encompasses a city of hipsters and technologists, a city with centuries of history and a bright future of growth. It is the perfect marriage, they say, of the glory days of old and the possibilities ahead.

My Tour de Taco, as I came to call it, took me from the humble taco truck to family establishments where English is not the first language, from hipster breweries to high-end establishments with expensive cocktails. My first stage began, appropriately, under the yellow jerseys once worn by a Tour de France champion, Austin’s own Lance Armstrong. His bike shop, Mellow Johnny’s, includes the in-store Juan Pelota Cafe, where the 2017 edition of the world’s most famous cycling race played, during my July visit, on a big screen above a handful of industrial metal tables.

The cafe serves breakfast tacos made by Veracruz, one of the city’s best-loved taco trucks. Refried beans, a light fluffy egg and cheese sit inside a perfect flour tortilla, wrapped to dip in a gentle red salsa. It is light enough to be a good breakfast without slowing me down ahead of a busy day (1-512-473-0222;

That evening, I meet a friend at Lazarus Brewery, a modern throwback space with a lumpy, handmade wooden bar and 13 beers on tap. We dive into homemade chips and a just-spicy-enough guacamole, beset on all sides by a hipster crowd in beards and glasses (1-512-394-7620;

The next morning, I drive across town to a local joint with quite the reputation. Joe’s Bakery has been a draw since the Avila family opened a small grocery store on the site in 1935. Today, a fourth generation of Avilas runs a bustling diner. The parking lot is full, and the line is out the door. Thanks to quick turnover, I’m seated in minutes on a red bar stool at the counter. The happy noise of a family breakfast joint envelops me.

My morning iced tea is delivered in a glass the size of a small bucket. The tortillas, crisp off the grill, have a massive scoop of barbacoa — never skip the recommended onion and cilantro — and a zesty green tomatillo sauce that adds moisture to dry eggs (1-512-472-0017;

For lunch, I stop at El Arroyo, the internet’s favorite taco bar. Positioned on a thoroughfare that guides traffic from Austin’s northern and western neighborhoods into downtown, the restaurant is known for its low-tech, black-letter sign, which is decorated each day with another joke: “Treat your mom to a margarita, you’re probably the reason she drinks.”

The bright yellow and blue walls, with green trim and orange accents, are obscured by the smoke wafting from passing platters of fajitas. The chef wears a shirt that reads “Body by Queso.” My al pastor taco is full of smoky pork, set off with the sweet crunch of pineapple (1-512-474-1222;

Hours later, I brave the crowds on 6th Street; its bars give Austin a reputation as a nightlife destination. I head to the Austin Taco Project, inside the Hilton Hotel, for my most upscale meal.

Here, executive chef Kevin Spencer, a self-described “taco-logist,” brings the fusion trend to tacos. The Pineapple Express, the typical combination of pork and pineapple, comes on a chewy and substantive corn tortilla. The Oc-Thai-Pus is unexpectedly meaty, and not as chewy as some octopus dishes, thanks to the crunchy garlic cashews. Coconut curry sauce in a saffron tortilla makes this the unique dish of the trip (1-512-682-2739;

On my final morning in Austin, I try Fresa’s, a drive-through and walk-up. Disney show tunes float on the air outside the brightly painted building as I eat at one of the few outdoor seats in the hours before it will become too hot. The green salsa that comes with my breakfast tacos is unexpectedly spicy. The Tricky combines avocado and egg; the Margie, with steak, eggs and mild peppers, is a medley of textures (1-512-428-5077;

Eager for one more stop, I head to Torchy’s, a local chain that started as a fast-food truck and now boasts locations as far away as Denver. My brother-in-law chooses the Brush Fire, full of Jamaican jerk chicken, and a Tipsy Chick, with fajita chicken and a bacon-bourbon marmalade. I go bipartisan: The Democrat has a scoop of barbacoa paired with avocado and cheese. The Republican has jalapeño sausage with cheese and tomatoes (

And so my Tour de Taco ends in flavorful victory. But after so many tacos — I count 14 during my stages — I am in no shape to think about pulling on the yellow jersey.
