But with banking executives tightening their purse strings, organisers have replaced the annual ball with a £100-a-head "no frills party" complete with finger food, a relaxed dress code - and free beer, courtesy of Cobra chief Karan Bilimoria. Corporate guests have been known to pay up to £20,000 for a table at the gala dinner and last year's ball was attended by the Queen of Bhutan, Ozwald Boateng, Meera Syal, author Gautam Malkani and a host of the country's wealthiest Asian tycoons.
