We went to Vegas to celebrate my birthday.We stayed at the Encore and SInatra's came highly recommended.....what a disappointment!!  We sat on the patio which was lovely, but the service was awful! Our server had no back up and she was serving 5 tables on her own! We waited 20min before we even were able to order a bottle of wine or cocktail. They were out of the wine we ordered ($52), so we had to order a more expensive bottle. We finally ordered the lasagna and the veal milanese..both house specialties...we were told. The lasagna was good, however our server offered to take it out of the casserole dish for me because it was too hot, but she never returned! The veal was awful and very expensive ($51)...it had absolutely no flavor and was tough. It was served with a tomato puree' instead of chopped tomatoes on the salad...it tasted like Campbell's tomato soup!We finally complained and then had several people come by to check on us. The manager offered to buy us a \""moscato\"" after dinner..but it was too little too late. They ruined my birthday dinner for $235.00! I should add that we are in the (Italian)restaurant business in New York. We dine out frequently and travel extensively...with all of the great restaurants and chefs in LV, I would pass on this one!
