Eating vegan is a trend that has been growing rapidly around the world.

Vegan fast-food chain By Chloe has rapidly grown from a single New York City location to a worldwide chain, with its first London location opening on February 6. It's drawn comparisons to McDonald's because of its popularity and expansion plans.

To see what the hype is all about, I went to a By Chloe restaurant to try some of the vegan fast food they offer.

Eating vegan is becoming more and more popular. A recent Nielsen report found that 40% of American consumers are actively trying to incorporate more vegan foods into their diets.

And By Chloe is trying to make the most of the trend. While it may not be "fast food" in the traditional sense, By Chloe serves inexpensive vegan food in a casual setup with a walk-up counter and strict no-reservation policy. Started in 2015 by Samantha Wasser and Chloe Coscarelli (who was later ousted from the company), By Chloe has transformed from a local vegan eatery in New York City to a worldwide fast food chain, with no plans of slowing down soon.

The chain now has 10 stores, including a new location in London, where another is on the way. On Thursday, By Chloe announced it had received $31 million in funding from investors including Bain Capital, Kitchen Fund, Collaborative Fund, and TGP International/Qoot International to expand to 20 locations in the US and internationally.

"We are actively looking for additional international locations but are taking it one store at a time ... we are very careful and intentional with each new location we select, and that will always be the case no matter how large we grow," Wasser told Business Insider in February.

The company takes an eco-friendly approach to fast food by using locally sourced ingredients that are 100% free of all animal products and served in recyclable packaging. The menu has a variety of burgers, pastas, french fries, salads, and sweets, and instead of soda, it offers pressed juices, teas, and coffee. A "Grab & Go" shelf has convenient salads and juices that are pre-packaged and ready to eat.

The London menu is nearly identical to the US menu, with the addition of local favorites like fish n' chips, shepherd's pie, and sticky toffee pudding.

I went to the chain's flagship location in New York's West Village to see what the vegan fast-food chain was like. Here's what I found:
