A really innovative idea for a comedy series, I came across 'Party Down' from absolutely nowhere after a friend's recommendation. Simply put, each episode is a different party that the Party Down team are catering for and every episode really is great. Personal highlights for me were Adam Scott as the main protagonist Henry, and Ken Marino as the cringe-worthy team manager Ron Donald. An honourable mention goes to Jane Lynch, simply because she's a great actress.
If you're looking for a comedy series that is funny and just plain different to other things out there right now, then you can't do much better than 'Party Down'.
