Be careful of the Pico! Hot Hot Hot!.
This is the best/authentic Mexican food I have ever had in Raleigh. The staff speaks both english and spanish, though the menu is in spanish. I've had a steak burrito and chorizo gorditas, both are excellent!
The Mexican Coke is a little sweeter than American.
Best tacos in Raleigh so far.
But who cares about the ambiance...we go for the food which is absolutely amazing. I find myself craving tacos from here all the time. My favorite are the tacos al pastor. Also, you should try the horchata (sorta milky drink) if you never have...it's amazing. Also try their bottled Coke which is Mexican style (uses real sugar instead of corn syrup).
The establishment is kind of like what you get at the mall food courts. You go up to the counter, order your food, they'll call your number, and you pick it up and find a table to sit down and eat. They have a condiments bar with limes, salsas, etc. to load up onto your taco.
This is real mexican food...unlike most of the mexican restaurants here in the Triangle (my wife is Mexican and she loves this place).
