Everyone must try the syrup flavoured coffee, Cafe Canadien. It's a little expensive, but it's absolutely worth it. The staff is very skilled in making not only the lattes and coffees taste good, but also give the top foam some artistic design.
The counter tables that are by the window are perfect if you want to work on your laptop and have a few glances at people walking on the street. Their big centre table is also good if you want to sit down and write.
