The UK Version of Kitchen Nightmares is much better than its US counterpart. Gordon lets the viewer in on actual business and cooking tips that are truly valuable for any Restaurant Owner or Aspiring Chef. Plus there is tons of swearing and you know he has that department covered as well! Another highlight is seeing some of these failing establishments and the general locales, and in many cases suprisingly charming.
Also I noticed Season 4 has music by DJ Shadow, Massive Attack and other Ninja Tune tracks as well.
