input: Write a function to implement a chatbot that can provide customer support in a restaurant. The function should read a user's question from a file named 'random_user_question.txt', generate a random response from a predefined list of possible responses, and then print the response.
  assert restaurant_chatbot("What meals do you serve?")=='We serve a variety of dishes - from salads to pizzas to steaks!'
  assert restaurant_chatbot("What dishes are available?")=='Check out our menu for a full list of options'
  assert restaurant_chatbot("What kinds of food do you offer?")=='We serve a variety of dishes, including traditional Italian, Mexican, and American fare. What would you like to try?'
  assert restaurant_chatbot("I am looking for something specific.")=='We have a great selection of meals! What kind of dish are you looking for?'
  assert restaurant_chatbot("Do you have anything special?")=='We have a unique selection of meals - have you checked out our menu?'
output: import random
