Wolfgang to Wolfgang -- Puck You

Wolfgang Puck is filing a lawsuit, claiming another Wolfgang has screwed him over.

According to the suit, which will be filed today in L.A. County Superior Court, Puck claims a guy named Wolfgang Zwiener opened a rival restaurant, Wolfgang's Steakhouse, just blocks from Spago in Bev Hills. According to the suit, one of the owner's of Wolfgang Steakhouse had a license to use the Spago trademark, but that expired last year.

Puck says the other Wolfgang is riding his lobster tails, confusing potential customers into thinking the Steakhouse is one of Puck's places.

A frustrated Puck says, "The most common reaction is, 'It says Wolfgang's Steakhouse and you are Wolfgang." We're thinking Mozart might have one up on him. Dude, you make pizzas.

The lawsuit claims trademark infringement and unfair competition. Wolfie wants an injunction.
