BBC's "50 things to eat before you die"

From what I understand, Guinea pig is really in markets in New York & New Jersey (heavy Peruvian immigration population).

Reindeer and Kangaroo may be easier to find than you think. Even in Columbus, Ohio, the large organic market (Short North) has a butcher that carries more exotic meats (boar and alligator are staples). They’ll order reindeer (which is good, by the by) and kangaroo for you.

You may even try a butcher shop – sometimes they can get more exotic meats from vendors.
