I recently had Senor Tequilla cater a group of 50 women engineers. You can't beat their price!
If you're looking for a TRUELY authetic mexican restraunt, this is is. But real mexican food can be rather bland & fatening... I found that the tortillas were homemade, but so thick that they were kinda chewy.
They also use a lot of fat... real lard... in their cooking. Again, this is part of the "authentic" mexican food... but I didn't care for it. Few spices are used, so while the food is inexpensive and filling, it lacks the flare you get at a more americanized "TexMex" place.
So if you're looking for authentic Mexican... this place is definately for you. But if you're looking for something that makes your mouth sing... try On The Border or Abuelo's.
