I'm also feeling indecisive - the existing alchemist and drunken boxer subclasses do decrease the unexplored archetypes available, if not the design space.

Some thoughts that have crossed my mind while considering have been:
Despite the existence of the Tavern Brawler feat, the rules I'm aware of don't offer much in the way of suggestions for how to make a tavern brawl a fun encounter.
The implied context of "hold my ale" is "watch me do something stupid and/or cool."
Meeting in a tavern is a classic way to start a campaign; what are some subclasses that might naturally hang out in that setting?
Other than alchemy, what might spellcasters use alcohol for? Is the Green Fairy a viable warlock Patron? Would a Fermentation druid by much different from a Spores druid?
I've already done a culinary arts bard; doing the same for bartending might be a retread

Leaning towards the Green Fairy patron.
