Five cents has never gone so far, when Taco Bueno restaurants turn this year’s Cinco de Mayo celebration into Cinco de Bueno.  On Saturday, May 4, and Sunday, May 5, participating Taco Bueno restaurants will debut an improved, bolder queso for only five cents a serving with the proceeds going to the Kansas Food Bank. And the richer, tastier queso isn’t all that will be bueno on that date. Taco Bueno will match all sales from the new queso offer for the participating eight food banks, making the day even “More Bueno.”
