A handy set of random tables that you can use whenever the party gets a thirst on, to enhance your alternate reality by giving them a proper drinking experience rather than a bland "You get some ales" and move on.
The first table is a combined one: roll percentage dice twice to determine a convincing name for a tavern whenever the party declares that they are looking for one. Some combinations will work better than others, but even if you are good at coming up with names on the fly this can be helpful especially if your characters are getting suspicious about finding a Sword and Board and The Broad Face (two tavern names I use quite often) in every settlement they visit!
Next is a table to determine the primary clientele, and this is followed by one with the intriguing title of 'Tavern is fresh out of...' You may prefer just to select whatever it is your adventurers (particularly the grumpy ones) like to order, else get your bones out and roll. The results offered are quite broad, so you may wish to use this table with caution - inns that are regularly out of essentials like ale do not keep their customers for long.
And so it goes on with further tables for Barkeep's Attitude, The Mysterious Person Drinking Alone in a Corner, The Facilities are a... (very useful for those who like an air of realism, if not a miasma in the privy - this has a subtable to determine how clean the rest facilities are), and for those who want more entertainment there are tables for games played in the establishment and that evening's live entertainment.
There's even a table for likely consequences for those who have a bit too much to drink; whilst you can also find out the name of the house drink, the atmosphere of the place, what accommodations are available and even which section of the community is not welcome at the tavern.
Overall very handy, generating enough for you to create a realistic establishment literally as the characters ride into town declaring that they need a drink!
