Can You Trust Google Maps Restaurant Reviews?

The top-rated Tex-Mex restaurant in Dallas, according to Google Maps, isn’t Mia’s. It isn’t Mariano’s, E Bar, or Las Palmas either.

It’s a place called Rj Mexican Cuisine, and there’s a good chance you’ve never eaten there.

As of April 13, Rj Mexican Cuisine carried a 4.8-star average across 11,252 Google Maps reviews, according to D Magazine. That’s more reviews than Mia’s, Mariano’s, E Bar, and Las Palmas combined, and a higher rating than any of them. For anyone who grew up eating queso at Mia’s on Lemmon or spending Friday nights at Mariano’s, that number stops you cold.

Something doesn’t add up.

The mechanics of review manipulation aren’t complicated once you understand how the incentive structure works. Restaurants can purchase review packages through third-party services, paying for clusters of five-star posts from accounts that appear legitimate. Google’s algorithms reward volume and recency, so a restaurant with thousands of glowing reviews outranks a decades-old institution with a fraction of that count, even if the older place has fed half of Preston Hollow at one point or another. The system doesn’t distinguish between a review written by someone who actually waited 45 minutes for a table and one typed by a contractor overseas who has never set foot in Dallas.

Dallas diners who rely on Google Maps to find a solid plate of enchiladas are essentially trusting a system that can be gamed for a few hundred dollars.

The stakes here aren’t just about bragging rights on a restaurant ranking page. Established Dallas institutions, the kind of places with regulars who’ve been coming since the 1980s, can lose foot traffic and new customer discovery to competitors who figured out the review-buying playbook. A visitor to Dallas searching for the best Tex-Mex in the city might drive past Mia’s on Lemmon to find a restaurant with 11,000 reviews that locals have never mentioned. That’s a real economic consequence for real Dallas businesses.

Google has published policies prohibiting fake and incentivized reviews, and the company periodically removes suspicious content through automated and manual systems. The Federal Trade Commission finalized a rule in 2024 banning fake reviews and testimonials, making it illegal for businesses to buy, create, or disseminate them. Enforcement against individual restaurant operators, though, is a different conversation from publishing a rule.

What can a careful diner do? Cross-referencing Google Maps ratings against Yelp, against food press coverage, and against the actual knowledge of people who live near the restaurant still works. So does ignoring the aggregate star number entirely and reading the text of individual reviews for specific detail. A review that mentions the name of a server, describes what the salsa tasted like, and notes the parking situation tends to reflect an actual visit. A review that says “amazing food great service highly recommend” could have come from anywhere.

For what it’s worth, the restaurants that Preston Hollow families have been driving to for decades earned those reputations without 11,000 reviews. Mia’s doesn’t need a star-count inflated by software. The plates do the talking, and so do the people waiting on the patio on a warm April Saturday, taking up every parking spot on Lemmon Avenue.

The Rj Mexican Cuisine story isn’t unique to Dallas. Review manipulation runs through the restaurant industry nationally, affecting searches in every major city. But Dallas diners have a particular advantage: this city has enough food reporters, enough obsessive regulars, and enough old-school word-of-mouth culture that the real lists still circulate. You just won’t find them on Google Maps.
