How can I stop repeating myself

def which_resturaunt():
    resturaunt = input("Do you want to go to McDonalds, Jimmy's seafood, Mickey's diner, John's steak, Joe's food court, Beacon Street Cafe, Arnold's bakey, or IHOP? ").lower()
    if resturaunt == "mcdonalds":
        input("""Do you want to order a:
        BigMac
        McNuggets
        grilled chicken
        Egg McMuffin
        Happy Meal
        """)
    elif resturaunt == "jimmy's seafood":
        input("""Do you want to order:
        Shrimp
        McNuggets
        grilled chicken
        Egg McMuffin
        Happy Meal
        """)
# so on, so on

And now, I'm going to have to start using ifs for if they pick the different food for every single resturaunt. I feel like I am definite;y violating the Dry policy (don't repeat yourself). Do you have any idea of how to use a function with parameters to solve this problem? Thanks!
Jack

Here's one idea: what if you have a dictionary where the keys are restaurants and the values are lists of menu items?
