Although the principal allure of this elite, upscale steakhouse is its unrivaled menu, the second floor piano bar also consistently delivers the liveliest lounge scene in all of 90210, where monied carnivores congregate to swill stiff drinks and pour fine wine. Classy, clubby, and a posh playground for sugar daddies, chic cougars, and gorgeous gold-diggers of each gender, it’s the sort of swank saloon that evokes Sinatra’s swinging heyday. And try, just try to stump impresario Gary Sherer at the piano – and the trumpet, and clarinet, and any other instrument he might decide to whip out – with your request: he has a 5,000-song repertoire.
