This is the best chain coffee shop (i.e. a coffee shop like Timothy's, Second Cup or Starbucks as opposed to little neighborhood cafes) that I've been to so far. It's cute, conveniently located, has free and fast wifi and friendly staff. It's also got a better selection of cakes than most other chain coffee shops. Their Chocolate Almond Cheesecake is really quite good (although I think they buy it frozen rather than fresh). In the summer they put out tables on the sidewalk, in the sun and this makes for a lovely way to get some sun and some work done.
All in all, I recommend this place both for meeting friends for a chat and for trying to get a bit of work done. I would also pop in for some of their cheesecake, if you like cake and cheese (who doesn't?).
