Mario Batali....what have you done?  I'm your biggest fan of Osteria Mozza in LA and was expecting Mozza quality and deliciousness at Carnevino.  With the quality of a Sizzler and the service of Olive Garden (actually although I hate their food, the service is even better), I am taking some of my \"I'm your foodie groupie\" points away big time!!  That's what happens when these great restaurant owners grow too quickly.  Service and quality goes way down.  :(  \n\nChris was our first waiter, but then we got stuck with Goose.  Rude, sarcastic, made racist jokes, just unbelievable.  Maybe he should have been stuffed and served on a platter instead of serving customers.  I can't imagine a guy like that making it at Macaroni Grill, let alone a Mario Batali restaurant.  \n\nOk, on to the food.  The steak tartare was decent, but it went down from there.  I ordered the lamb chops as my entree.  As many others said, they WAY undercook things.  I asked for medium rare, but the meat was oozing with blood!  Yuck!  And it was at least 75% fat.  Fortunately, Chris came to the rescue when he sent it back to the kitchen for me and took it off the bill.  I had ordered the brussel spouts as a side.  They were mediocre at best.  Needless to say, I skipped on the dessert.  Mr. Batali...please, don't ruin the image I've had of you.  Keep a few restaurants that you can manage and consistently deliver Mozza quality.  Otherwise, you will be boxed in with the Outback Steakhouse & Olive Garden.  Fortunately, Osteria Mozza is still 5 stars in my book.
