Jon Basso, owner of the Heart Attack Grill in Chandler, Florida and proud creator of the quadruple bypass burger (see picture) is suing his counterpart, who recently started a similarly-themed establishment, the Heart Stoppers Sports Grill, in nearby Delray Beach.

The Heart Attack Grill has been around for years. Heart Stoppers began serving it’s artery-clogging, stomach-expanding fare in the past few months.

Both establishments feature Hooter’s-like “nurses” as waitresses and a cardiovascular-catastrophe themed ambiance, which prompted the lawyer representing the Heart Attack Grill to plead his case thusly to the South Florida Sun Sentinel:

“Heart Attack Grill is the originator of the medically themed hamburger grill and restaurant. … It sells high-calorie food products and we have had very extensive media coverage, including numerous shows on the Travel Channel and the Food Network. In my mind, we are just as well known as McDonald’s.”

According to the WSJ Health Blog, the Heart Stoppers folks were negotiating for a Heart Attack Grill franchise before cutting and running. The Heart Stoppers theme “is completely different,” says the lawyer for the upstart. “They didn’t steal the same trademarked Single Bypass, Double Bypass burger”

And Heart Stoppers offers food for vegetarians as well, claimed Iggy Lena, the owner.
