Some time ago, someone recommended a Mexican place called Azteca on Main St. in Mt. Kisco. We got a chance to try it last week, and we're grateful for the recommendation: Great stuff! The mole is marvelous. The tacos are authentic and wonderful. Chorizo is very fine.
This isn't a fancy place: basically a scruffy diner for the local Mexican laborers, as far as I could see. But it doesn't matter: The food is great.
