We met a friend for coffee at Buena Vista Social Cafe, a Cuban-themed restaurant in Green Point. The decor is what I'd expect to find in an old Cuban bar; the best part of all is the old leather couches and chairs - like those you'd expect to find at your grandmother's house - making up a corner lounge-area, where you can enjoy drinks without having to sit at a table.
Buena Vista is a really nice place to visit, and if you've never been there before you should make a turn (and try the lamb and feta nachos!). Just be warned that the restaurant doesn't have a non-smoking section (which I thought wasn't allowed these days), so if you have an allergic reaction to cigars and cigarettes then best check that there aren't too many people smoking when you arrive.
Now that I think of it, perhaps the reason they're able to get away with a fully-smoking restaurant is because of the Cuban theme - you kind of expect to see people smoking cigars in a Cuban bar, don't you?
