I want to know the answer to the following question:
What is a professional called at a restaurant who advises customers about beer and food pairs?
All the background I'm provided with is that "Various social traditions and activities are associated with beer drinking, such as playing cards, darts, or other pub games; attending beer festivals; engaging in zythology (the study of beer); visiting a series of pubs in one evening; visiting breweries; beer-oriented tourism; or rating beer.". Is that enough to answer the question?
Answer: no
