Former Stranger writer Sean Nelson once wrote that Next Level Burger "turns out to be a fantastic innovation for those of us whose brains know eating animals is indefensible but whose hearts still can't get past the idea that a cheeseburger, fries (or, better yet, tots!), and a milkshake is nature's perfect meal." The plant-based fast food chain will celebrate the grand opening of its new flagship Ballard Blocks location with free burgers and swag for the first 100 people in line, $25 gift cards for the first 10 people in line, free vegan hot chocolate, and a chance for all guests to win a $100 gift card. Not only that, but they'll also have a DJ, eco-friendly balloon animals, and face painting. Ten percent of the day's proceeds will benefit the Seattle Humane Society.
