James Martin hits the East Coast of the USA with a visit to the historic city of Boston. James's American Adventure in Boston starts with a shopping spree in the public market; he also visits an innovative restaurant where cocktails are inhaled rather than drunk and has baked goods supplied by Joanne Chang, a Harvard graduate who has made a name for herself with a string of successful bakeries. James's tour of the city isn't complete without a trip to Fenway Park, the home of the Boston Red Sox.
