This is always a hit. It's my go-to Mexican restaurant in the area, and the food never disappoints. I wouldn't call it terribly unique, but the food is really, really solid and they have lots of great options. I love the taco salads and enchiladas especially.
The one thing I can't figure out is their salsa strategy. There are chips and two different types of salsa. One is served in a little cup and is way too spicy for me. The other (delicious salsa) is served in a carafe, so you have to pour it in something to use it. Puzzling, but not a huge problem. I definitely recommend Ajo Al's.
