Which logical fallacy is used in the text?
I'm not surprised, frankly, that someone who gets lost in his own neighborhood would argue that New York has better pizza than Chicago.

 - ad hominem: a personal attack against one's opponent
 - circular reasoning: an argument that supports a claim with the claim itself
The text argues that people who like New York pizza are likely to have a poor sense of direction. This is a personal attack that isn't relevant to which type of pizza is better. This illustrates a type of logical fallacy known as ad hominem.
