Kevin Hart will open a new plant-based fast food restaurant called Hart House, beginning this summer with locations in Los Angeles and Hollywood. The comedian, actor and Philly native started eating a plant-based diet in recent years. For the new restaurant, called Hart House, he tapped former Burger King Chef Michael Salem to develop the menu, which will include a range of 100% plant-based burgers, sandwiches, nuggets, milkshakes and other items.
