You won't get far while you're traveling without some good meals, and the Spanish-speaking world offers plenty to dazzle your taste buds. Cuisines vary widely, influenced by geography, ethnicity, and cultural history. So, peruse those menus, ask questions about ingredients and seasonings, sample local specialties, and visit the markets. Try unusual things: guinea pig in the Andes, iguana in Mexico, fried ants in Colombia; if the locals eat it, it must be food!
