This is the absolute worst location I've ever been to. I switched to the hualapai location after too many poor experiences at this Charleston (shell) location, but tonight was reminded why I dislike this one so much when the bf picked up food from here. The rolled tacos are lacking in meat and poorly made (nearly every one of the dozen times I've ordered it here), they hardly put any guacamole on the food, and tonight they actually melted cheese over guacamole making for a goopy, warm, weird consistency of melted cheese and guacamole. There are many other complaints, but I don't want to get going. If you want Robertos in the Summerlin area I would drive to the hualapai location, only 2 miles away from this one. And it has a drive thru too!
