I was just there last week/weekend. Didn't see traffic as any greater issue than anywhere else, but knew what roads to avoid.... there's always several ways to go. Saw so many exotics that it became a yawn. Denis and I were sitting in a restaraunt in Westwood and saw a brand new (still temp tagged) Ferrari 458 drive by, with a new M3 in chase. Saw a new Porsche GT RS 4.0, a Carrera GT, Rolls Royce Phantom, and the list goes on.....
Paid $3.49 for gas, which is 20 cents more than home, but that's still less than 10% more. Paid $120 a night for a four star hotel downtown (Westin). Food is the same as anywhere.
Maybe we were just in two different parts of the city, or have different perspectives/baselines
