A 30-pound burrito and one margarita are the only things standing between you and owning part of a restaurant.

That's the pitch one Mexican restaurant in Brooklyn has for the brave at heart (and stomach). For $150, Don Chingon patrons can take a stab at eating the toddler-size burrito made with steak, chicken, pork, rice, beans, salsa and drinking a ghost pepper margarita. Upon successful completion, the challenge's winner will get 10 percent ownership of the restaurant.

"Don Chingon is a modern taqueria, so we take a lot of traditional recipes and put our own spin on them," owner Victor Robey told CNBC during an interview at the restaurant. "… This is basically a modern take on an eating challenge."

Robey expects only the best competitive eaters to be able to handle such a challenge by themselves. Small groups can win prizes such as cash and t-shirts but not a stake in the restaurant, he said.

"While we don't just want to give away the restaurant, we do want someone with that kind of eating credibility to come in and give it their best shot," he said.

(For comparison, a Chipotle chicken burrito with white rice, black beans, vegetables, salsa, cheese, guacamole and lettuce weighs in a paltry 1.72 pounds.)

Complicating matters, contestants must complete the challenge in under an hour without any bathroom breaks or discharge of bodily fluids. The restaurant also will not accept responsibility for illness or death incurred while participating in the challenge.

George Shea, a partner in the International Federation of Competitive Eating, calls the contest a "great PR stunt."

"What they've done is take the challenge to an absurd level, and it's funny," he said.

So, with such a daunting task, does Shea really think anyone could win?

"There's no human alive who could eat a 30-pound burrito, in my opinion. But I've been proven wrong before," Shea said.
