I'm a tea guy, but I decided to get a siphon the first time I came here, just to see it made. It didn't disappoint.
The staff here are serious about their coffee (as you expect from this sort of place), and provide good conversation to go with the java.
The space is really diverse, from the bright bar up against the entrance window, to the large table in the main room to the cozy basement area with plenty of seating area. All good spots to catch up in some reading, hang out or do work.
If you can, budget some time towards walking around the surrounding blocks (at least in nice weather), as there's quite a bit to see around.
