I'd describe the vibe as wealthy, crunchy, low key , generally well travelled locals and friendly, at least in my experience as a frequent visitor. The taxes are very high (I know, duh) but no one seems to complain, unlike other places in NJ. There are fun places to eat in the boro and it's a very walkable downtown with a pedestrian mall. The only thing I've heard locals complain bitterly about is the lack of parking at the local train station.
