Ubuntu Hour is a monthly meet-up, mostly just for hanging out and socializing. If you've got a technical problem you want advice on, feel free to bring it along, but mostly we're just getting the local community to talk about whatever.
I'm going to suggest Al Madina's, at Phillip and University. I know they have wifi. I'll check at lunch if they have power. They're mostly a take-out Egyptian place, but you can get baklavas or other deserts or snacks.
