There are actually four Wolfgang Puck-branded venues in DTD. One is the Wolfgang Puck Café, which is over on the West Side end of things. There is the Wolfgang Puck Dining Room, which is upstairs from the Café and has a more upscale feel and menu. There is also a Wolfgang Puck Express in the same building.
Over in the Marketplace section of DTD, there is another Wolfgang Puck Express.
The Express locations are CS, while the others are TS and would need a reservation.
