Substance Diner serves up delicious and flavorful vegan comfort food that will excite anyone's plate. Their sandwiches, including the vegan Philly cheesesteak, are absolutely to die for. The diner offers a cozy spot, tucked away behind Screwbean Brewery, where you can order food and have it delivered to the restaurant or brewery. The friendly staff will help you navigate the menu, which features tasty options like spicy "chicken" sandwiches, crispy fries, and fresh kale salads. Don't forget to try their chocolate shake! Whether you're vegan or not, Substance Diner is a must-visit for a great plant-based getaway from the norm.
