BEVERLY HILLS. Try as you might, it’s nearly impossible to name any place in Beverly Hills that packs in as many dealmakers and power brokers as the Polo Lounge. The bar is actually a piece of Hollywood history thanks to its roster of past and present patrons. Treat yourself to a martini or any other drink from the full list of cocktails, beers, and wines ­ you’ll most likely leave with just as many memories of the atmosphere as of the drinks. Service is impeccable even if you’re not a star.
