I'm posting this before lunch so you can get over to one of the Houston Pollo Campero locations for free chicken today! It's not just for Houston, but all of the company's restaurants across the nation. Naturally there are some limits.

I was working at KTRK when the first Houston location opened. We did a story on it. There was a line of cars extending down Bellaire for weeks trying to get into the restaurant. I believe this is a Latin American restaurant, so it coming here is like you living in another country and the first McDonald's opening. You'd probably be in line too for a taste of home.
