Great little cafe, nice atmosphere, wifi free with food or drink purchase and available in their gorgeous back garden too! Evenings usually have performances/music, so laptop use after 7pm may be hard. Bring outlet extender (1 to 2) & you can use their table lamp outlets.
Nice neighborhood cafe. The sign says Chats Cafe, but the locals call it Cafe No Underpants. Service varies depending on who is working, but I've found the wifi to be dependable there. Ask the person working for the WEP key.
3rd floor of the Virgin Megastore. The signs downstairs say "Free WiFi with purchase", but really, if you're in a cafe that's providing wireless, you're going to buy a coffee, right?
I think this is free always -- when I logged on, I was redirected to a page that asked me to pick between "One day free," and an "Access code." I would imagine if I came back tomorrow, I could just re-select the one-day-free option. Maybe I will need to clear cookies.
