That is not how OOP works. describe_restaurant is method of class Restaurant. You need to create an instance of the class then call the method

class Restaurant():
    """Restaurant example"""
     
    def __init__(self, restaurant_name, cuisine_type):
        """Initialize restaurant name and cuisine type attributes"""
        self.name = restaurant_name
        self.type = cuisine_type
         
    def describe_restaurant(self):
        """Tells the name and type of restaurant"""
        print(self.name.title() + " has " + self.type.title() + " food.")
         
    def open_restaurant(self):
        """Tells that the restaurant is open"""
        print(self.name.title() + " is now open!")

restaurant = Restaurant('saltgrass', 'steak')
another_restaurant = Restaurant('Great Dracon', 'chinese')

restaurant.describe_restaurant()
another_restaurant.describe_restaurant()
restaurant.open_restaurant()
another_restaurant.open_restaurant()

Output:
Saltgrass has Steak food.
Great Dracon has Chinese food.
Saltgrass is now open!
Great Dracon is now open!

Awesome thanks much!
