My wife and I decided to try La Cave for a belated birthday dinner celebration after reading the rave reviews on yelp and other sites.  We are longtime Vegas vacationers who love staying at the Wynn because we appreciate their high standards, quality amenities and top-notch service, and love to frequent their excellent restaurants.  It started out fairly well--the greeters at the door welcomed us and seated us quickly, and our server came and took our drink order.  All of the restaurant staff was impeccably attired and gave me the feeling that this was going to be a good evening.  While walking to our table, we noticed that most of the employees were busy chatting away with each other instead of working or doting of their customers, and most of them avoided eye contact or any kind of acknowledgement of us--yes, we WERE properly attired.  The restaurant was very stylish and clean, and our table for two was set very romantically and the ambient lighting was perfect.  However, the huge flatscreen TV on the wall blaring out a March Madness college basketball game was confusing and somewhat of an eye (and ear) sore, since we wanted to dine in a cozy, romantic restaurant--not a sports bar.  Our drinks were came quickly and were really good--I had the Rince Cochon, a strong Belgian ale, while my wife had a glass of Eckstein Riesling.  Our server asked if we were ready to order, but we were unfamiliar with their offerings and requested a little more time.  Well, I finished over half of my beer by the time she finally reappeared to take our food order.  We had a small order since we needed to get to a show after dinner, so we ordered the jumbo lump crab lettuce cups, warm salt-roasted beets, chicken flatbread and the beef filet.  The crab lettuce cups came out first--full of succulent lump crabmeat, topped with small wedges of mandarin orange and pink grapefruit--very tasty and refreshing!  Next, the chicken flatbread and beef filet--the flatbread was very generous and filling, the exotic seasonings and hearty portion of chicken made it most delicious and a worthwhile experience, while the beef filet was savory and rich, sitting on crostini soaked with those delicious beef juices, topped with blue cheese and cooked to a perfect medium.  After we finished the three dishes and our drinks, we patiently waited for another 10 minutes before our server showed up and asked if we were ready for dessert.  I quietly mentioned to her that she forgot the roasted beets, so she said she would check on them.  Wait 5 more minutes, then she comes back and says she forgot the beets but if I still wanted them \"the guys could throw them on the grill\"--what?!  I was still hungry (these ARE small plates, after all) so I said I did want them.  Another 10+ minutes later, the beets finally show up, but it is kinda sad sitting and eating beets with nothing else to munch on with it. So I quickly ate most of the beets and asked for the check, since we still had a show to attend and our discombobulated meal took over 75 minutes to consume.  To my surprise, I was charged for the beets!  We wanted to speak to a manager about our disappointing experience, but needed to rush out of the restaurant to get to the show at The Orleans in time, which we did with just minutes to spare.  So I would rate La Cave the following:\n\nFOOD:  4 stars-excellent quality, but very expensive for small plates.\n\nAMBIENCE:  3 stars-nice atmosphere and lighting, staff dressed very well, but sports-bar TV's killed it.\n\nPRESENTATION:  4 stars-very professional, clean and stylish.\n\nSERVICE:  1 star-extremely disappointing for a Wynn restaurant; too long wait times for food and service followup; felt server wanted to rush us out.\n\nTo say we were disappointed is an understatement, because the food offerings and the restaurant itself were wonderful.  Hope La Cave can clean up their service issues, because there are a lot of other options, both on- and off-property.
