This is a fantastic place to get work done. I was probably the most annoying, loudest person there - looking for a good seat (close to a plug because my battery was dead), asking about the wifi, bumping the table a few too many times.
The barista was extremely friendly considering how annoying I was. My latte was delicious, and just the right size. I was able to get a lot of work done in the silence.
The washroom was far, far away (down the hall, down the stairs... across the river, up a mountain) - so plan accordingly.
