I want to say that I'm a frequent diner at the Mastro's in costa mesa as well as beverly hills.
The service there trumps the vegas experience. Disappointing. At one point the server dropped some of the gnocchi on my lap as he was serving it onto my plate. He knew because I reacted unfavorably since I had some pretty nice pants on. Not a single apology.
meh.
I don't hold it against you Mastro's... you're still my 2nd favorite place to eat in orange county :D
