hey i don't think people use different words for foods like 'burger' or 'pepperoni pizza' in different languages.. dunno why ordering food should be such a problem B.T.W. pizza isn't an english word
Hamburguesa is Hamburger in Spanish and papas fritas is fries. A beer is cervesa and gracias is thank you. That's all you need to know.
