Zaba's is a very mediocre version of Chipotle/Cafe Rio but with a few more options than the typical build your own Americanized Mexican food chain. The meat is sub-par at best but I do enjoy their shrimp. Their pico de gallo has no flavor but their medium-hot verde salsa is a great mix of flavor & heat. They do provide more options when it comes to toppings, like regular & sweet potatoes, roasted jalapeños & multiple sauces.
If you're a guacamole fan, like most Chipotle goers do NOT chose Zaba's over Chipotle or Cafe Rio. $1.39 for a small size & boy is it small. I think Zaba's is a good place to try out for a different option of the same but there are definitely better places out there.
