Millions of Americans watch what they eat. But one Las Vegas man has painfully discovered that where you eat can have a big impact on your health as well. In a story almost too bizarre to be true, a man suffered a heart attack after eating a "triple bypass burger" at the Heart Attack Grill in downtown Las Vegas, local affiliate Fox5 reports.

As comically tragic as that may sound, no one can sue the restaurant for not issuing fair warning. Its website proudly proclaims the menu offers, "Taste Worth Dying For!" (Fortunately, the man in question survived his attack.)

Still, it was the first actual known cardiac incident at the Heart Attack Grill. "He was having the sweats and shaking," "Nurse" Bridgett, who was working at the restaurant at the time of the incident, told Fox5. (Employees at the restaurant are given fake medical titles, including the establishment's owner, "Doctor" Jon Basso.)

"I actually felt horrible for the gentleman because the tourists were taking photos of him as if it were some type of stunt. Even with our own morbid sense of humor, we would never pull a stunt like that," Bosso told Fox5. "He was sweating, suffering. Anyone with an ounce of compassion would've felt for him."

Basso said the man's name is being kept private but that he is recovering from the heart attack.

Of course, you can't blame patrons for being caught up in the overwhelming sense of irony. Not only is the restaurant named the Heart Attack Grill, but its sign tells prospective diners that anyone "over 350 pounds eats free." There's even a tongue-in-cheek warning sign at the restaurant's door stating that the offered dining fare is a health risk.

Some of the menu items available for diners at the Heart Attack Grill include: The butterfat milkshake, non-filtered cigarettes, "flatliner" fries and four different burgers, each rated on an ascending scale of one bypass to the quadruple bypass burger.
