It will depend on your city, but public libraries are usually fantastic. The wifi is free, the seating is spacious, and everyone is there with a purpose. They also cost nothing and you never get the "am I loitering?" feeling that you get in coffee shops.

University libraries can also be good, but be mindful of the date. If it's exam season I tend to avoid them simply because students should have priority to the libraries they are paying for.
