Mystery Diners

Sour Grapes (2x9)

Air date: Dec 21, 2012

Scott, the owner of Rhythm Kitchen in Las Vegas, suspects his sophisticated, but slightly arrogant, wine sommelier is somehow negatively affecting spirit sales. But could he also be selling his own wine to customers and keeping the profits? Charles sends Mystery Diners Chelsea and Hollie in as customers to see if something smells rotten.
