Can anyone recommend a good cafe or other place to just sit and relax?

Ideally I'm looking for somewhere in east or north Oshawa, Courtice or Bowmanville, to go to just sit, get a tea and maybe something small to eat, and spend some time relaxing/working. That being said, anywhere relatively quiet and indoors would work.

I know there's plenty of places like Tim's or McDonald's, but I want somewhere that's not disgustingly corporate and won't be super busy to avoid too much distraction. That being said, I also don't want to be taking up space for too long at a really small business that needs the space for other people.

I'm going to have some time on Saturday afternoon, after work, so it needs to be somewhere that's open into late afternoon.

Any suggestions would be appreciated.
