This is my third time dining here and I had to write in because reviews don't give credit where it is absolutely due. The service is quick, efficient and to the point. They have redone the entire interior and exterior and it is always extremely clean. I ordered the fajitas and my girlfriend the chimichangas. Both were fresh and flavorful. I think some of the hipsters on yelp need to realize they're not paying big money when they walk through the doors and to expect just what si señor's advertises.. authentic Mexican cuisine.
As far as the food being bland I find this to be false. The flavor comes from the main ingredients and if you want to spice things up feel free to use one of their hot sauces. Otherwise, as in the case of my fajitas, the flavor of chicken, green bell peppers, sweet onion, guacamole, beans, cheese and sour cream with a dash of hot sauce left me satisfied. The portions are large and come out quickly.
If you want authentic classical Mexican look no further this place is awesome. Well done si señor I look forward to stopping back soon and can't wait for the weather to warm back up to enjoy one too many pitchers of margaritas. The bottom line: Try this place out if you aren't a stiff and enjoy classical Mexican!
