Ruth Chris Philadelphia Riesling Wine?

Hi! I was at the Ruth Chris in Philadelphia and had a glass of their house Riesling...does anyone know what the name of it is? Thanks!|||Riesling, Hogue, Columbia Valley, WA|||Philly in the house too. go to Columbus Blvd to the Liquor Outlet and find all the Reislings, if you are familar with Delaware, go to Naaman's Rd in Claymont and go to Total Wines and taste them all, plus the workers are very knowledgeable.
