This is a rather average location of a rather average chain. Like all other locations there is free wifi and an unobtrusive playlist. The coffee isn't good, but some flavors are drinkable with enough doctoring. Pastries and food are typically stale and expensive and should be avoided by discerning customers.
In this location there are plenty of seats, and seats of different types (comfy chairs, bar, normal tables, patio) so getting a seat is not hard. To work here is a bit difficult because there doesn't seem to be plugs throughout most of the place. It's noisier than most locations inside, and being at the corner of Bathurst and King sitting outside is really not an option if you plan to be able to hear anything besides traffic.
Second Cup cafes serve a limited range of standard cafe purposes, and this one is really only good as a place to kill time or meet somebody...and hop on the internet for a while if you need to check something or knock out a few emails.
