Stop in to one of Just Salad's two Manhattan locations and you'll walk away with your lunch in one of these colorful, reusable bowls. According to co-founders Nick Kenner and Rob Crespi, Just Salad's signature bowls are part of the company's effort to be environmentally friendly and encourage green practices amongst its customers. As incentive for customers to reuse their bowls, Just Salad offers two free toppings to those who do.
