If you are a big fan of cilantro (I am not). you will probably enjoy the soup. Frankly, I find a little of that particular herb goes a long way, so a dish with that as it's principal flavor is not my cup of broth.
As for the rest, "Peruvian chicken" is indistinguishable from pretty much any other rotisserie chicken, including the grocery store variety, except that the birds might actually run a little scrawnier. (Possibly attributable to those high Andes elevations? Ok, no.)
Anyway, the offerings that are different from other places are unremarkable - pretty bland mixings involving rice, french fries, or flavorless pasta.
Service was fine for a drive-through, but I'm afraid I'll be making this one a drive-by.
