Good restaurants for groups?

Hi all,

I could use a little help narrowing down some restaurant options for a birthday dinner with a group of approximately 15 people. Ideally, here is the criteria I'm looking for:
- Somewhere on strip
- A good environment for semi-mature birthday party shenanigans (group average age is around 30). So some place that can accommodate seating, along with a nice vibe is preferred
- Cuisine - open here, but nothing too exotic (just to help cater to the numerous tastes within the group).
- NOT a prix-fixe menu (or at least options for individual orders to be placed)
- Budget of < $100/person

If people have any experience or guidance on restaurants which might be suitable, I'd appreciate it! TIA!

 

Striphouse in PH has a seperate, enclosed room. I've had a large/loud group in there and it worked out very well.
Rao's in Caesars has a seperate room near the front. Again, it is good for a large group.

 

Carmine's at the Caesars' Forum Shops might hit the spot. All portions are shareable at reasonable price.

 

The Prime Rib Loft at the Orleans

 

Thanks for the suggestions all
