Ask HN: How do you tackle the "where do we head out today" problem?

I'm really curious about this problem as I'm yet to find a service that solves it well for me. To elaborate, it could apply to just a couple of individuals or a larger group looking for a good place to head to at the end of the day / on a weekend. And the agenda could be anything from just hanging out to dinner to a rock gig to a movie to a more formal event. From what I've gathered thus far, most folks I've discussed this with 1) ask a friend for a recommendation 2) look up Yelp or a similar service 3) subscribe to a newsletter like Thrillist or Urban Daddy or Startup Digest so they're more informed 4) actively monitor Plancast, Facebook Events and the like. I'd really like to know whether this more or less covers the entire gamut of available alternatives. I'd love to discover services that tackle this well that I don't know about yet, because this seems to be the "can't get it out of my head" idea for a few months running.
