input: Write a function to implement a chatbot that provides customer support for a restaurant based on a user's question read from a file named "random_user_question.txt". The chatbot should respond with one of several pre-defined answers chosen randomly from a list. The function should read the user's question, select a random response, and print it.
  assert chatbot_response("What meals do you serve?") == 'We serve a variety of dishes, including traditional Italian, Mexican, and American fare. What would you like to try?'
  assert chatbot_response("Do you have any vegan options?") == 'Check out our menu for a full list of options'
  assert chatbot_response("Can you recommend a dish?") == 'We have a great selection of meals! What kind of dish are you looking for?'
  assert chatbot_response("") == 'We have a unique selection of meals - have you checked out our menu?'
output: import random
