Yes it is "gimmicky".. isn't that what Vegas is all about? It is really beautiful, and a fun place to see and visit. We perused all 3 levels, settled in at the top (it was 2 in the afternoon, so "ambience" did not matter so much to us at this point). Temps outside at 117 deg. F., so we were hot and thirsty.
Todd was our bartender, and did an excellent job of attending to our needs. My hubs ordered a Mojito, which he declared to be the "best I've ever had".
I actually only drank Seven-Up.. was too hung over and hot for anything else. But loved visiting here, really spectacular.
