Grey London, sponsor of Marketing's Power 100, hosted the evenings for the illustrious marketers listed in the table, and some of marketing's finest - including London 2012 Olympics bid chief executive Keith Mills, COI head honcho Alan Bishop and PepsiCo chief Martin Glenn - sat down to a sumptuous meal of sashimi, sushi, black cod with miso and chocolate bento boxes washed down with lychee martinis.
But there was one celebrity guest we weren't banking on. Marketing editor Craig Smith's welcome speech included a quip about David Beckham - number 100 on the Power 100 list - not being able to make it. However, a listening waitress let slip that Mrs Becks was, in fact, dining in just the next room. The former Posh Spice even allowed one member of Marketing's editorial team to show her the way from the loo back to the restaurant (which, as any Nobu regular knows, is pretty confusing).
In fact, it emerged that Posh was supposed to be picking up a prize at the Pantene Pro-V Awards over at the Royal Albert Hall, but had sent her sister along in her place to receive it because she was, er, in Madrid.
Her appearance at Nobu instead had the tabloids in a tizz the next day.
But Mix reckons that Posh clearly knew where the real power lay that night.
