On the philosophy section of their website, west~bourne says "We embrace the free thinking and open possibility of the west coast." You should embrace the free thinking and possibility of a first date (fingers crossed it goes well) and grab a komboucha or a brew here. You can pretend you and your date are LA chillers rather than uptight New Yorkers who both have a pitch deck due at 7AM.
Drink
Well curated non-alcoholic drink menu - coffee, kombucha, tea. Plus a compact beer and wine list.
Eat
Socal inspired vegetarian fare, served all day (Yes, you can get waffles on your post-work date, and yes - you should).
Sit
A large, high top communal table and booths. Not a huge space but you should usually be able to snag a spot for you and your date.
