Bennu Coffee. Free fast WiFi. Extremely good coffees and teas as well as decent food. Comfortable chairs and tables for working, writing, and connecting.
Transit system is practically non-existent. With the exception of one train line going from downtown to NW Leander. There is a slow bus system. Great for downtown only. Locals use RideAustin, GetMe, Fasten, and to a smaller degree Uber and Lyft.
