When you're craving shredded beef tacos, chicken enchiladas, arroz y frijoles, Yuliana's will satisfy. The food tastes like what you'd expect to find at a decent sit-down Mexican restaurant in AZ, but they do it quickly and at fair prices. In Gilbert, there's not a huge selection of authentic tasting taco shops, so Yuliana's is a great find.
My favorite item here is the shredded beef crispy taco. Take a look at their combo list and you're sure to find something you like. My daughter loves the rice and beans, preferably mixed up together. The rest of my family usually eats the cheese enchiladas.
The only real drawback is that the interior is somewhat lacking in aesthetic. It's not the kind of place where you'd hunker down for chips and salsa while listening to a mariachi band before your entree arrives. This is a "Mexican food stat" type establishment. So, get your items to go and listen to your own mariachi music at home.
After reading other reviews, I'm looking forward to trying a burrito in the future. Until then, salud!
