Union Street offers great boutique shopping, yummy restaurants and cafes, and busy bars. It is blocks from the Marina and Bay. The only downside (besides, of course, parking) is that Union Street is full of poseurs. Yeah, that's right. It's just a bit uppity and unnecessarily snobbish or my taste. I enjoy going there, but don't ever spend too much time there. The attitude on the street reeks of elitism.
