Not knowing Mexican food very well, I went for #7 - Chicken enchilada with mole sauce like the legend said. It was rich and sweet, only a tad spicy. Quite tasty. It is now priced at $10.50 (+ tax & tip). Had the portion size been bigger it would have deserved a 4/5. Food prepared and served by a kind smiling Chinese lady.
The place wasn't sketchy at all, probably cleaned up since the first reviews. I found it amusing though that the registration papers for the establishment is issued for a dépanneur with limited-seating food service.
