Make your own study-abroad immersion program

I want to keep learning Hebrew, but this isn't so much the moment to run off and join a kibbutz (or become an Israeli Air Force pilot, as Matthew Yglesias suggests I do, what with my perfect vision and, well, right of return). So I'm taking an Ulpan here in NYC, and today did my homework at an Israeli coffee bar on the Upper East Side. Yes, such a thing exists. Everyone's speaking Hebrew, which made for useful background noise. Plus, the iced coffee there is most excellent. The place also sells some kind of pre-made s'mores, which certainly looked intriguing, but which most likely would have gotten stuck in my notebook.
