My friend just moved to New Hempstead and she's very chassidish (yiddish speaking, tights from 3, band on hat, etc). She has a few neighbors like that as well. Her husband's shul is about 8 minutes away. I think there's also a small garage style shul closer.
Her main issue is with her son's bussing to yeshiva. Otherwise she loves it.
Speigel's shul in New Hempstead is very chasiddish. There are afew smaller shuls in houses as New Hempstead is a big area. In New City, most chassidish live in one area, the shul is somewhere off West Clarkstown.
