We had seen the commercials for this place often, so we thought we would try it for lunch.  We discovered this was not a good idea.  First we waited in the front to be seated while no one even noticed us for about 5 minutes, and we were the only ones there. Then the plates on the table had greasy marks all over them, and my napkin was wet before I even sat down.  The salsa tasted like it was from a jar and the bean dip was fairly flavorless.  The chips were fine.  I ordered two ground beef tacos with rice and beans.  I thought how wrong could I go with this?  It was the worst taco I have ever had in my life.  It was greasy and gristly.  The beef had a horrible flavor.  The side of beans tasted like a glob of refried beans from a can, and ironically were the only thing I could choke down.  I was also surprised at the higher prices than I had anticipated.  I feel completely ripped off by this experience and will never, ever go to Arriba anywhere again.  Try Serranos for a cheaper much tastier and cleaner experience!
