My two paulista girlfriends and I were going for drinks after work, and I was staying in Jardins. They chose Quinta da Mandioca, and they chose well.
Not only does it have a nationalistic flair (naming itself after manioc, a potato-like tuber that is part of the local cuisine), but there are plenty of tables where groups may sit, the snack menu is fantastic (selections range from the greasy to the light), the drinks are yum, and it's in a great neighborhood close to many other restaurants and bars. I think you can even order dinner if you wish.
Apart from the excellent conversation I had with my friends, the thing I remember the most about this restaurant is the leafy decoration. Were they bamboos or just giant potted ficas? I can't recall, but that's just a recommendation for the strength of Quinta do Mandioca's caipirinhas!
