You wouldn't expect it judging by the exterior/interior design and the corny iridescent spanish colors, but the flavors were for the most part authentic and tasty.
I ordered the Chile Relleno and taco combo which came with rice and beans. The plate was more than enough for one person. The rice was light and flavorful -- even the beans which I don't typically eat were good.
My friend ordered the carne asada burrito and it just didn't compare to the combo. Definitely go with the combos here.
