Just a week after Mikhail Prokhorov spent nearly $19,000 on lunch at Nello’s, fellow Russian billionaire Roman Abramovich just splurged $47,221 there, mostly on vintage wines and magnums of Cristal at $5,000 a pop. While Prokhorov was described as the richest man in Russia when he made a deal to buy the New Jersey Nets, Abramovich is said to be worth $8.5 billion. His entourage, including pregnant girlfriend Dasha Zukhova, covered two tables. “I’m not impressed. I’m happy,” Nello Balan told us “The only thing that would impress me is a $1 million tab.”
