For a takeout americano = 5 stars
For sit-in: a disaster. They seem to actively want people to not be here. It's always too hot, partly because there's no AC, but also because the heating is cranked in winter. The music is too loud, at least when the employees can stop fiddling with what's playing as if the teenagers passing the aux cord around at a party.
The coffee is really good! They just seem to want nobody to drink one... in which case, why open a coffee shop?
