I've been to Kiva Han twice and each time I left disappointed and a little grossed out.  First of all, the baristas were having a personal conversation at the front counter and ended up getting my drink wrong, which I didn't notice until after I had left.  Second, on both occasions the women's bathroom was beyond disgusting.  It's covered with purposeful graffiti which is meant to come across as I'm-trying-to-be-very-hip-and-rebellious but instead comes across as a poor excuse not to keep it clean.  One of the bathroom sink knobs is torn off and coated in I don't know what, the toilet seat is the kind you don't want to sit on so you end up hovering over it, and the front cover on the toilet paper dispenser is torn off which makes me very afraid that the tp (if even there at all) has spent some time on the floor.  To top it all off, the coffee isn't anything to brag about--not terrible but not great either.
