An ANTIQUES ROADSHOW special edition, "Tasty Treasures" celebrates the season with a cornucopia of appetizing antiques and delectable collectibles for and about eating and drinking. Plucked from ROADSHOW's appraisal archive, highlights include a coveted stainless steel 1930s meat serving cart that saw decades of use at a Reno, Nevada, casino; a rare toy coffee service made of 18th-century British porcelain; and an heirloom Tlingit Indian oil bowl and ladle, acquired by the owner's great-great-grandfather during a military posting to Sitka, Alaska, in 1877, valued at a jaw-dropping $250,000 to $300,000.
