How did we pick these?
We started from the ground rather than from a list. Every address and phone number below was pulled from the business's own website where one exists, then checked against something that is not a review aggregator: the San Antonio Current's 2026 readers' poll, MySA's reporting, the Live From The Southside guide to local barbacoa, and the Current's survey of city tortillerias. Where hours conflicted between sources, and on the South Side they almost always do, we described the pattern and told you to call.
More candidates failed that test than passed it, which is the real story of researching this neighbourhood in 2026.
- Carnitas Lonja, 1107 Roosevelt Avenue, is the one everybody still recommends. MySA reported it closing for good in December 2023 after six years, and the building was later listed for lease. It is gone.
- Lala's Gorditas, 1600 Roosevelt Avenue, closed permanently on December 24, 2024 when owner Steven Pizzini retired. KSAT and KENS both covered it.
- 4 Missions Cafe on Southton Road shows up high in review sites and has no website, no published phone number and no independent coverage we could find, so we could not verify it.
- Las Tapatias de Jalisco has a South St Mary's Street room across from Brackenridge High School that locals rate, but we could not confirm a street address and phone from a source we trust, so it waits.
No partners, clients or sponsored listings appear here. Nothing in our client file matched San Antonio and Mexican food, so nothing was pre-filled and nothing was removed for a relationship. This is a straight editorial list.
Where does the South Side actually start?
Ask three people and you will get three answers. For this guide we used it the way readers searching for it mean it: everything south of downtown. That takes in Lavaca and Southtown, where Mixtli and The Haven sit within a few blocks of each other, the Nogalitos and South Flores corridors, the Roosevelt Avenue run out through Harlandale, and the Mission Historic District down by Mission Concepcion and Mission San Jose.
If you want the stricter definition, drop Mixtli and The Haven and you still have five kitchens that have been feeding the Harlandale and Mission side of town for between two and five decades.
What should you know before you go?
This is a daytime part of town for eating. Barbacoa sells out, counters close at three, and the one evening option needs a ticket bought in advance.
| Where | Neighborhood | Best for | When it is open |
| Mixtli | Lavaca | A long evening meal | Tuesday to Saturday, ticket only |
| Rios Southtown Barbacoa | South Flores | Weekend barbacoa by the pound | Weekend mornings until sellout |
| Nicha's | Harlandale | Barbacoa and house tortillas | Call, hours vary by listing |
| The Haven Southtown | Lavaca | Breakfast and menudo | Mornings, later Friday and Saturday |
| Tommy's | Nogalitos | Breakfast tacos | Daily, closes 3 p.m. |
| Del Rio Tortilla Factory | Gillette Blvd | Tortillas and tamales to take home | Call, no hours posted |
| Fruteria La Mission | Mission district | Fruit cups and aguas frescas | Most days except Tuesday |
Two things worth planning around. Weekend barbacoa in San Antonio is a race, not a brunch, and 7.30 a.m. is a normal time to arrive. And the Mission Historic District stop pairs naturally with the missions themselves, which are free to enter and five minutes from Fruteria La Mission.
What should you do next?
Pick a Saturday. Be at Rios Southtown Barbacoa by eight, take a pound of barbacoa and a dozen tortillas, then drive south to Mission San Jose and work your way down the mission trail with a fruit cup from La Mission. That is the South Side in one morning and it costs almost nothing.
Book Mixtli separately, as its own evening, weeks out. For the rest of the city, our guide to the best things to do in San Antonio besides the River Walk covers where to spend the hours in between, and there is more in our San Antonio coverage, across Mexican food statewide and down the road in New Braunfels.
