The Best indeed.
The food is great and the food is even better, the only draw back to this one is that since as I have stated the food and the service are beyond compare, your timing is important to get parking. If your looking for taco Belltype food, then go elseware! this chain is of the highest quality!
Better than a poke in the eye with a sharp stick.
Nico's has good quality food with big portions for those looking to expand their waistband. Since nobody cooks in Oro Valley this place is always hopping. Limited seating but people come and go quickly. Highly recommend the carnitas make sure you ask for lemon. Food quality is always consistant, hot and tasty. Bummed that Nico's doesn't do a chili relleno like other fast mex joints do around town.
It would be nice if they added a fresh condiment bar with fresh fried jalapenos, cut radish, marinated onions, and the other fare. There is a chain in Phoenix called Tacos Jalisco that serves similar food but adds the condiment bar and serves cold cervesa. Fat chance that Nicos could ever get a beer wine license in Oro Valley.
