There are some really nice coffee shops that offer alcoholic drinks as well, which is really good if you want a place where you can sit quietly, or if you want to go out with a business associate etc. Most cafès are open until 1am, but you can always find a bar open late if you're not ready to go home yet.

Most cafes also offer food, from bakery goods to full meals. The meals don't tend to be of restaurant quality, but they are cheap and cheerful.
