Good choice if you don't like EDM/House..club caters to people who like hip-hop and top40.
Don't expect any extravagant decor like xS or Marquee. Good open layout, so even if it gets crowded, you can still move around easily on the sides.
Table locations and booths are scattered everywhere. If you're on a budget but want bottle service, it's easy to get a deal at 1OAK. Great VIP hosts will work with you. I didn't encounter any power tripping doormen/security on both my visits.
They do get celebrities in here all the time..Lil Wayne, Usher, etc. have been featured guests.
Again, not exactly on my top 5 list when going clubbin in Vegas, but 1OAK is a solid tier-2 spot. Not much of a hassle to get inside and the lower bottle minimums make it attractive. 4 stars is being generous, but I have had a great time everytime I visit.
