I really like the starbucks in Alexandra House/Landmark. It's absolutely HUGE and has a ton of nice sofa areas to sit at. The place also clears out around 7 so it's pretty easy to get a seat after that. I'm not sure if it closes early though. Does anyone know?
If anyone here is allergic to starbucks, the best bet would be to find a quiet bar before the evening rush hits, which probably means somewhere without a crazy happy hour. I think the problem with a cafe would be that most of them would be doing dinner and probably wouldn't appreciate a bunch of people just sitting around drinking coffee! Unless we wanted to do dinner too...
