It is really enjoyable to have a cafe located inside the library in case you have a sudden coffee craving. In addition to an extensive drinks menu they also serve other little snacks like fruit snacks, granola bars, cookies, and pastries as well as breakfast wraps and other sandwiches.
Like the library, the cafe has free wifi inside (with your library card). There are some seats inside, but there is also an enjoyable outdoor patio area connected to the cafe. The prices are reasonable and the staff is friendly. Win-win.
