Pedro's Tacos, San Clemente, CA

This place is legit.

Walk up to the window to place your order, then eat on the bench outside. There are no tables or bathrooms. 

Cash only, but there is an ATM next to the pick up window.

For less than a buck you can add potatoes to your taco or burrito.  This is definitely the way to go. 

Grab a taco where the locals go. You won't be disappointed.
