We frequent Ocean's Scottsdale and it is always an excellent experience, great food, wonderful atmosphere. We thought Ocean's Las Vegas...Shouldn't we expect the same? The doorway leading to the restaurant is warm and welcoming and the staff are truly professional and friendly.  We thought memorable anniversary!  It is when you walk into the open-space leading into the shopping mall that you feel like you are in a crazy, expensive food court. Actually, MUCH noisier than a food court. Cavernous and noisy!  We needed to shout at each other so we ate mostly in silence.  Some areas are undercover and possibly they were less noisy.  We do not mind paying top dollar for an aged steak cooked to perfection or an excellent martini... and, the food here was excellent however we rated this lowest of low for ambience. Noise level? Think NASCAR
