Do you like being surrounded by pretentious, wayyyy-over-it douches? That's the question you have to ask yourself. Some people gravitate to that. If you like that, and you like to overpay for a nice atmosphere and location, great! If not, skip.
I am often in TO and work remotely, have been here a few times. The staff is SO much cooler than you are and they will get to you WHEN they get to you. Think what you would expect to pay for any item and then add $2-$4. The patrons are the people you would expect to gravitate to such a place, and need a LOT of attention. I sit in the window and look out or it's difficult to work, what with the staff and patrons needing everyone within sight to know how absolutely amazing and right-on they are.
Still, big windows and lots of sunlight, stools with backs... if you sit in the window and look out, you can work well and pretend you're not in the douche vortex.
