that's nacho cheese
I love Mexico but MAN oh MAN are things messed up there. Check this gem from the WSJ:
Days after the Casino Royale fire, Monterrey's leading newspaper published a video showing the brother of the PAN mayor of Monterrey, Fernando Larrazabal, receiving wads of money at one Monterrey casino. The paper suggested that many of the city's casinos, which lack legal permits, were paying off city officials—and drug gangs—to stay open.
The mayor has denied wrongdoing. His brother, Jonas Larrazabal, says the money was payment for selling cheese to the casinos.
There is a grand Mexican tradition of the politician's brother as bagman (Raul Salinas, you KNOW I'm talking about you), and apparently the PAN is not immune to it.
The whole article is interesting and depressing. A thriving illegal casino industry operates with impunity across the nation.
