"NO SALADS!" screams the sign on the wall. "MIX DRINKS NOT MORALS" yells another sign behind the bar.

And with that, the tone is set for a meal at Doomie's, a no-meat fast food joint in Parkdale that is as forceful about what's on its menu as what's not.

Doomie's is part of a trend in Toronto that's seen veganism take an abrasive turn, with so-called "extreme vegan" cooks pushing in-your-face ethics, making the case that not eating animals is a morally superior lifestyle.

And to even the chef's surprise, the vegan-or-nothing attitude is not putting off restaurant goers. In fact, judging by the lineups, it's attracting them.

"I want someone who isn't vegan to say, 'That's a good burger,' not 'That's a good vegan burger," Chef Doomie says.

No eggs

Jeff Merkel wears combat boots in his food-truck — not traditional combat boots, though. They're vegan combat boots with not a stitch of leather to be found on them.

Merkel says his truck will be Toronto's first all-vegan mobile restaurant when he gets his mobile food license, which he hopes will happen in June. The non-leather boots and his vegan cooking symbolize Merkel's attitude toward food: he is a self-described vegan extremist, an avowed enemy of meat-eating. And fittingly, he's called his food truck The Vegan Extremist.

"We took a risk with the marking idea," Merkel admitted. "But that's who I am."

Merkel only had a brief restaurant career before launching his food truck. He was working in the kitchen of a gastropub, surrounded by meat. "It was gross. Brisket, hamburgers. I couldn't be there," he said.

The 24-year-old has always been vegan, but he was also always careful about leaving meat-eaters alone. That is, until recently.

"Vegans have the reputation of being in other people's business telling them what to eat," he said. Because of that reputation, he was often criticized for trying to push his food choices on others, even when he wasn't.

"People were accusing me of it anyway, so I thought, 'Why don't I just embrace the whole vegan extremist thing?'"

Merkel specializes in South Asian-style curries, minus any animal products. He makes chana masala, baingan bharta, Thai yellow curry, samosas, paratha bread, rice and desserts.

When he started, he figured he'd anger some people. Meat-eaters can be defensive, he agreed.

"I expected at least once or twice that someone throws an egg at us," he said. "But not once."

Extreme goes mainstream

Meantime, back at Doomie's on Queen Street West, the chef has no trouble answering when asked, "Who would have expected a three-hour wait to get into an all-vegan diner in Parkdale?"

"We did," said Chef Doomie.

The name Chef Doomie is an alter-ego, and he would not reveal his real name or any personal details for this article.

He got the idea for his namesake restaurant in Los Angeles. "I have always been in relationships with vegetarians and vegans, and when we would go out to restaurants, I was always disappointed. The restaurants were horrible to me," he said.

Doomie decided to open up Doomie's, an all-vegan option in the Hollywood neighbourhood of Los Angeles. It mimics more traditional fast food, with triple-decker burgers flooded with special sauce, messy Philly cheese steaks, thick boozy milkshakes and huge portions of all of the above.

Doomie's restaurant expanded to Toronto this spring, but in this city, the restaurant is more evangelical about veganism.

That part is thanks to Hellenic Vincent De Paul, a co-owner with Chef Doomie. "We're unapologetically vegan because people confuse vegan as a diet and it's more than that. It is a moral stance people take to end the suffering of animals."

That partially explains the 'no salad' rule.

As Chef Doomie explains it, there are two types of vegans: the people who do not eat animal products to be healthy, and those who make the ethical choice not to slaughter animals for food. There are more ethical vegans than health-based ones, said Chef Doomie, and they don't necessarily want salads. They too crave junk food.

"The way I see it, the standard of vegan restaurants in the past is that vegans will come eat anything. They don't have options. So if you have mediocre vegan food, they're going to come eat it," he said.

Becoming vegan, one selfie at a time

Both the Vegan Extremist and Doomie's are selling the idea of a slaughter-free future as much as they are vegan food.

Merkel said most of society believes vegans "have long hair, wear purple tied-dye shirts and live at peace in the woods." If that was ever a reality, it's not any more, he said.

"You have a moral imperative to eat vegan," he said. "You don't have to adopt a silly lifestyle where you go camping and sing around a fire pit."

So far, his plant-based menu and "extremist" take has received only positive reactions, with an unexpected number of people stopping to take selfies with him and his truck.

It's all an effort to stop the killing of animals.

"People who are vegans for ethical reasons see it as a moral issue much like they see any other type of injustice whether it's racism, sexism or anything else," said De Paul. "In the same manner that we know that there will always be people who are racist or sexist, it doesn't mean they should stop or be deterred by that."
