When Nicole Marquis moved home to Philadelphia after college in California, she went from studying theater to educating her dad on the health benefits of a plant-based diet.
At the time, her father was battling high blood pressure, high cholesterol and a new diabetes diagnosis. He blamed genetics, she blamed his diet — so she bought him a blender.
All it took was one green smoothie, “and he was hooked,” said Marquis, now a Philadelphia-based restaurateur.
Within two months of adopting a plant-based diet, Marquis said her dad lost 25 pounds and was able to safely eliminate four of his medications. For a period of time, he also put his Type 2 diabetes in remission.
“I knew at that moment, I needed to bring this to millions of people everywhere,” Marquis said.
And that’s exactly what she did with her “fast food” concept, . On July 24, Marquis is opening the restaurant’s seventh location — and second D.C. outpost — on Connecticut Avenue NW, just south of Dupont Circle.
The menu at HipCityVeg, which launched in Philadelphia in 2012, is filled with American classics, such as a crispy chicken sandwich with ranch, and a smokehouse burger, topped with a tangy barbecue sauce and crispy onions. There are breakfast sandwiches, salads, shakes, fries — even nuggets for the kids and kids at heart.
But there’s one main difference in the food served at HipCityVeg, compared to other bun-sandwich establishments: Everything is plant-based. Organic soy, grains and veggies take the place of beef and chicken; soy ice cream is used for the base of the milkshakes.

Marquis said the burger- and fry-focused menu design was intentional: Serving ingredients that might be new to the masses in a familiar form makes plant-based eating more approachable.
“[Customers] can say, ‘Yeah, I know what a chicken-ranch sandwich might taste like. They pair that with a green smoothie, and that creates a domino affect in people’s lives,” said Marquis who sells the same green smoothie at HipCityVeg that first turned her father’s health around years ago.
“When they can eat a plant-based meal and be satisfied … they start to bring in more of that into their lives and we see that here.”
A published in 2018 in the journal Public Health Nutrition found that two-thirds of American adults surveyed reduced meat consumption in the last three years. Some are cutting back on animal protein for health reasons; others are reducing meat consumption for environmental reasons. According to from the United Nations, cattle-rearing generates more greenhouse gas emissions than transportation.

Marquis said most of the customers that visit HipCityVeg aren’t vegans: They’re omnivores who are interested in incorporating more meatless meals in their diet.
“People who just want a better option to the burger that they might choose down the road. I think when given the choice, people will choose plant-based foods as long as it tastes good and it’s convenient,” she said.
“Plant-based is the future.”
D.C.’s new HipCityVeg location opens July 24 at 1300 Connecticut Ave. NW. The first 100 customers get a free lunch; everyone else gets free fries all day.
