Agave is always a hit. We take most of our guests here. Great quality of food, incredible family recipes (enjococado and quality mole), hot homemade chips that comes with a couple salsa types, actual quality vegetable/vegetarian options, good tequila selection, nice service, and i could go on and on! We love the patio too, and almost always can sit right away.
As a celiac in a family of celiacs/gluten sensitive folks, it's awesome that the chips are gluten free which isn't always the case. They have lots of options for people sensitive to gluten. I have eaten there fairly often for many years, and as far as i can tell, i haven't been "glutened" there.
If i had any drawbacks at all, it's that sometimes service is slow due to being short staffed but honestly i see that pretty much everywhere. If you let them know about a time constraint they will kindly help out.
Whenever my family comes in town, they want to go to agave!
