If you are a fan of authentic Mexican food, you've got to try Tonayan in Rohnert Park. I've driven by this restaurant, located in the Raley's shopping center for the past year and had no clue what I was missing. The place is very unassuming, a converted diner that could have housed an IHOP or Denny's, which is one of the reasons I never stopped in.
My first experience last night was utterly amazing. The owner, Isidrio, hails from the town in Sonora, Tonayan, the restaurant's namesake. The serivce is awesome - attentive and friendly without being overbearing. Isidrio makes it his responsibility to make sure everybody is happy, and well fed with huge portion sizes and most entrees <$12 and under.
I had "El Jefe" a giant combination of Carne Asada, Black Beans, Rice, a perfectly cooked Chile Relleno, delicious Chicken Burrito, and Steak Taco, all for only $12.95! I was only able to eat about 1/3 and have lunch and dinner covered for today! My boyfriend ordered the Steak Fajitas, which were served with warm corn tortillas, and also perfectly seasoned and cooked.
All in all, this beats any local Mexican food restaurant, and I've tried most!
