When you are ready for a snack you can visit any one of the people carrying trays on their heads who are selling a variety of tasty treats such as salty cheese, juices, home made donuts, and peanut butter balls in white chocolate chips with a rum sauce that is to die for.    When you arrive in Central America you can have an appetizer of fried tortillas that will keep you satisfied until dinner time which is a long way off because you have a busy schedule and need to get some things done before you can relax.  Guatemala City has a bustling market place that is full of Mayan people dressed in colorful traditional garb.
