Uncle Berto's is tucked into a side of a strip mall and on first glance appears to be a chain, but is actually a local restaurant run by very friendly folks. We visited two times and have pleased with everything we ordered with one exception.
On our first visit we both had quesadillas, my wife had chicken and I had chorizo. Both were very tasty. You are also served complimentary chips with bean dip, plus there's a salsa bar.
On our second trip, I had a California burrito with chorizo and my wife ordered a tostada with beef and a taco with pastor (seasoned pork). Although I preferred my previous order of chorizo quesadilla, everything this trip was also very good with one exception: the taco was soggy. Overall, I can recommend Uncle Berto's for anyone looking for something other than your usual order by the number Mexican restaurant. As a side note, on both our visits a lot of Hispanics were eating here, so I guess that says something for the authenticity of Uncle Bertos'
