We met at this lounge two days before my wedding in Las Vegas so my friends and family could have a few drinks together, and for some so they could meet before the wedding. The staff at Hyde treated us great, though there was only 1 server for about 20 of us. We were given a reserved section of tables overlooking the fountains, thanks (I think) to the concierge at the Platinum Hotel who set it up. The view was fantastic, as was the band that started playing later on in the evening. I couldn't have asked for a better surroundings.
The downsides: the food was just OK. The drinks were tasty but between 15 and 20$ each - if you are from a smaller city this seems outrageous, but on the strip it turned out to be pretty standard.
