All the posts are here!
Here is a list of all the cafes/venues on Caffeine86 from the Americas, sorted by country/region, and then in alphabetical order.
So far: United States of America (3).
Those with “**” (two asterisks) next to them have, to my knowledge, permanently closed.
Those with “+” (a plus sign) next to them have, again to my knowledge, relocated so technically still exists but will be different from the one in the post.
