The World's Most Expensive Food, Channel 4, 8pm

Ever wanted to taste an 1811 cognac? If you have and you're a connoisseur, you'll know if costs around £5000 a glass. That's beyond the reach of most normal people, but not the many billionaires who now call London home. They and their very particular tastes in food and drink are the subject of this two-part series, which will either harden your resolve to foment revolt and bring about the end of capitalism - or shore up your belief that anyone who spends £325 on a single cup of coffee is too stupid to bother about. Tonight's first episode looks at the network of private food suppliers that keeps these moneyed metropolitans in luxury victuals.

Murder In Successville, BBC Three, 10pm

Billed by one critic as a (*takes deep breath*) "mixed-up structured reality comedy cop drama impressions show", MiS centres on a fictional town called Successville, a mad-as-a-tree fictional detective called DI Sleet (played by stand-up comedian Tom Davis) and a population of celebrities who are all played by actors. Got that? Then it throws a real-life celebrity into the action playing his or her self and lets the mayhem unfold. Last week we had the stupid posh guy from Made In Chelsea (hardly narrows it down, does it?) and tonight it's the turn of Radio 1 DJ Greg James to take on the role of Sleet's uniformed partner. His task? To try to work out why Reese Witherspoon has been murdered - though not before he's had to practice hostage negotiation with an inflatable doll while Sleet pretends to be a Mexican gangster who sounds Chinese. It's a lot more bonkers than it sounds.
