Hot beverages have been served long before Sheldon Cooper of The Big Bang Theory [DVD BIG] learned of their social benefits (as taught by his mother).
Even longer before Starbucks or Dunkin' Donuts, there were tea and coffee shops. The University of Cambridge recently posted an article about a archeological find of the remnants of one such 18th century coffeehouse. A cache of 500 related items were discovered, including 78 teapots. I found the article fascinating!
we have several books on hot beverages in the 641 section. Look for one of these on your next visit:
