I have one really close and have been meaning to try it out. Keep forgetting.
...and I meant to bump this thread some weeks ago, because I finally tried
Pollo Campero. A new one opened up a few blocks from me. The 4 piece chicken with 2 sides is really the best deal, and actually cheaper to buy 2 of those than the 8 pieces + 2 sides combo (You also get 2 more sides...for less!). You can mix the chicken styles.
The roasted isn't terrible, but it isn't special. At least, compared to the local wood or coal-fired peruvian chicken joints that litter the area, it really isn't worth it. The fried chicken is GREAT though. really enjoy it. Not so much the sides...little variety, nothing amazing.
