Every time I drive down East Speedway past North Columbus Boulevard I notice the yellow sign for Rilibertoβs Fresh Mexican Food and wonder if this is really, really Bertoβs.
I mean, Rili??
The quick-serve Mexican restaurants with names that end in ββbertoβ have been a phenomenon in the Southwestern states for decades. They go back to the Robertoβs Taco Shop chain that started in San Diego in the 1960s.
The surviving co-founder of that chain, Dolores Robledo, died July 14 in San Diego. But the phenomenon she and her late husband, Roberto, established just keeps spreading, in Tucson and around Arizona.
As my colleague Gabriela Rico reported last week, another three restaurants derived from that original chain β in this case three new Filibertoβs restaurants β are opening soon in Tucson, along with a fourth in Douglas.
Other versions of the format also keep popping up. In Tucson, in addition to Rilibertoβs, we have had Ralibertoβs and, more recently, Losbertos, an apparent takeoff on the more locally familiar Los Betos name. Nicoβs Taco Shop, it turns out, is also a descendent of the Robertoβs chain, but without the Berto name.

Filibertoβs has come to dominate the Bertoβs market in Arizona but nearly lost its trademark.
In Southern California, theyβve documented up to 18 versions of the name, including Rambertoβs, Roybertoβs and Deibertoβs. In northeastern Arizona, Alibertoβs is common.
In reality, theyβre all pretty much the same concept: burritos, tacos, enchiladas, quesadillas and breakfast burritos served 24 hours a day, seven days a week, on disposable plates at reasonable prices, or in bags at the drive-thru.
Most of the signs have a Berto name in a cursive script in red, yellow and green colors. When you see those signs, you pretty much know what youβre going to get.
But it was a new idea when Roberto and Dolores Robledo bought their first restaurant in 1964, their son, Reynaldo Robledo, told me Friday.
βI wouldnβt say they invented a format. What Robertoβs was really known for was, we were a 24-hours-a-day, seven-days-a-week taco shop. That became popular with kids going out for the night, after bars closed and stuff. We were open for them.β

An east-side Losbertos β not to be confused with Los Betos.
Roberto Robledo was from a rancho β a small rural settlement β in San Luis PotosΓ state in central Mexico, Reynaldo told me.
βWhen my dad opened the stores, he started bringing relatives from this ranch to come and work for him,β Reynaldo Robledo said. βHe would also bring other people to come work for him. Then in 1975-1976, he rented a store to his cousin Juan Diego Rodriguez.β
Thatβs how the ownership spread, Reynaldo explained: His dad would rent a store to someone else, not formally franchise it, and sometimes they branched out on their own.
A dispute over one of Rodriguezβs stores led to him changing the name to Albertoβs, Reynaldo Robledo explained. Legend says Rodriguez didnβt want to spend much money making the change, so he simply took some paint and changed the βRβ and βoβ in Robertoβs to an βAβ and an βlβ. With that, the first descendent of the Robertoβs chain was born β Albertoβs β and it spread fast across Southern California.

About 10 Nicoβs eateries β descendents of the Robertoβs chain β are in the Tucson area now.
As time went on, they all brought relatives and friends from San Luis PotosΓ to start new restaurants, and gradually some of them branched off with new names. A well-known Robertoβs on Mission Boulevard in San Diego is now called Ruribertoβs.
βMy dad was OK with that,β Robledo said of the proliferating versions of his concept. βMy dad saw it as him helping people from his own ranch to establish their own businesses.β
In Arizona, Filibertoβs was one of the first of the same kind to be established. It wasnβt a direct descendent of Robertoβs, Robledo said, but the main founder is married to one of the Robledosβ cousins and is from two ranches north of the Robledosβ original home in San Luis PotosΓ.
Founded in 1993 by four brothers from the Tenorio family, Filibertoβs has come to dominate the Bertoβs market in Arizona.
Soon after the company began expanding, though, it ran into trouble: First, the founders were indicted in 1997 for employing unauthorized workers, an indictment that led to misdemeanor convictions and to three of them being deported.
They also lost legal control of the trademark for Filibertoβs. It took years of legal battles for them to get it back, a case that ended in 2005, said Mark Weiss, a Scottsdale attorney who represented the owners of Filibertoβs in the case and remains the companyβs statutory agent.
Once in a while, theyβve had to defend the trademark from imitators, Weiss said. One Phoenix-area entrepreneur started a restaurant named Juliobertoβs with a script and sign that looked exactly like Filibertoβs. A cease-and-desist letter helped take care of that, Weiss said.
Despite its rough patch, Filibertoβs has kept growing, and is now at more than 55 restaurants in three states. It has six in the Tucson area before the next three are established
Nicoβs Taco Shop is an earlier, more direct descendant of Robertoβs but has not spread as much. Founder Nicolas CarreΓ³n worked for the Robledos, Reynaldo Robledo said.
In 1982, CarreΓ³n opened a shop in California before later moving to Tucson, said the current owner, the brother of founder Nicolas CarreΓ³n, who died in 2013. Coincidentally, the current ownerβs name is Filiberto CarreΓ³n.
Nicoβs has about 10 stores in the Tucson area now.
But now the competition isnβt just from fellow Potosinos, as people from San Luis PotosΓ are known. The Tucson Rilibertoβs, it turns out, is run by Indian-American Dhruve Patel. In fact, Rilibertoβs is the only Bertoβs chain I know of with restaurants in India. Among the items on the international menu: masala crunchy tacos.
Patel, who has owned the franchise for about year, said his understanding is that Rilibertoβs is the concept of a partner who broke away from Filibertoβs.
I had a burrito from Rilibertoβs Friday, and it tasted good β similar to a burrito from Filibertoβs, Nicoβs or Robertoβs.
But I know if I were marketing the place, Iβd look at how pervasive the Bertoβs name has become, and Iβd claim itβs the real, essential thing β that itβs Really Bertoβs.
