4.5 stars
As of right now, I think Omnia may be my favorite nightclub at Vegas and rightfully so. It is beautifullllll. High ceilings. Consistent and reliable air conditioning. Intricate and detailed decorations scattered throughout the building. Nice and friendly staff members. Everything was top notch.
At first, it may be quite overwhelming with all the rooms and it does seem like a maze at first. However, you will most likely get the hang out of it. I liked the placement of the DJ booth because it seems like they are closer to the crowd than wayyyy up there like in the other clubs. Also, I never once got bored because there was so much stuff to look that. The chandelier is absolutely mesmerizing to watch and is definitely the main attraction of the club.
The Heart of Omnia was a favorite amongst my group of friends. It plays primarily hip hop music and has a completely different vibe than the main dance room. If you are coming with a large group, a table/bottle service seems like the way to go.
I took off 0.5 stars because of the wait and hassle to get in. We were herded like cattle trying to get into the main club from the outside balcony.
Oh by the way, they WILL turn guys away if you do not have appropriate shoes.
