How Confident Is This Information?

Domingo is better documented than most for dietary needs, but “well documented” still isn’t “guaranteed safe.” Here’s the actual strength of evidence per diet.

Vegetarian

🥗
High Confidence

Listed as vegetarian-friendly across Tripadvisor, OpenTable, and menu aggregators, with clear meat-free options like the Quinoa Chili Bowl, salads, and street corn.

3+ independent sources agree

Gluten-Free

🌾
Medium-High Confidence

Ranked among San Antonio’s best GF restaurants; diners repeatedly praise knowledgeable servers and house-made blue corn tortillas. But no GF menu, no dedicated fryer.

Many consistent diner reports

Vegan

🌱
Medium Confidence

Officially lists “vegan options,” but specific dedicated vegan dishes are thinner in the reports — expect to modify vegetarian plates and confirm dairy substitutions.

Listed, fewer dish-level details

Celiac (Cross-Contact)

⚠️
Caution — Not Dedicated

Most celiac diners report no issues and cautious staff, but this is not a dedicated GF facility and there’s no separate fryer — one diner reported a cross-contact slip.

Mostly positive, some risk reported

Filter the Menu by Diet

Based on Domingo’s published menu and diner reports as of July 2026. “GF (modify)” means diners report it can be made gluten-free on request, not that it’s GF as served. Always confirm with your server — recipes and sourcing change.

No dishes match this filter right now — Domingo’s menu rotates seasonally.

How to Order Safely at Domingo

  • Lead with the blue corn tortillas. Domingo makes its own blue corn tortillas, which are naturally gluten-free — diners specifically flag the short rib quesadilla (made with them) as a safe GF pick. When in doubt, ask what’s built on corn vs. wheat.
  • Servers are your best tool here. Report after report describes staff who know which dishes are GF and proactively ask about celiac and cross-contamination. Tell them directly — GF items are not marked on the printed menu.
  • No dedicated fryer. Anything fried carries shared-oil cross-contact risk. If you’re celiac, skip fried items or confirm preparation first.
  • Watch the marinades and sauces. As with most Mexican-Southwestern kitchens, sauces and marinades are the hidden gluten source — ask before assuming a naturally-GF protein is safe as plated.
  • Celiac: call ahead for the quietest service. The kitchen is described as cautious but shared. A weekday visit gives staff more time to accommodate than a packed weekend brunch. See hours and the phone number.
How we built the confidence scores Each diet is scored by how many independent sources agree and whether diner reports contradict each other — Domingo scores higher than most because its GF reports are numerous and consistent.
Why “GF on request” is separate We split truly gluten-free dishes from ones diners say can be modified. The distinction matters: a modified dish depends on the kitchen getting the request right that day.
Menu changes seasonally Domingo rotates its menu. Treat this as a snapshot from our last check — see the value and price guide for current pricing.
