It's going to be a madhouse at the Ybor City Saturday Morning Market this weekend. Not only is Top Chef: The Tour making a stop at the weekly fresh market, but Mayor Pam Iorio is scheduled to board the 18-wheeler and join chefs Richard Blaise and Carlos Fernandez for their 10:30 a.m. demo. Reserved seating is no longer available, but show up early and claim your spot. (No telling how early that will need to be at this point.)
