Being a Vegas local and frequent strip club patron, I have been to them all. Little Darlings WAS always "the" place to go if someone in the group was under 21. ...Was.
The nature of the beast is there will always be some girls that hustle, upsell and outright snatch your cash; that's all clubs however the last few times here it is every single girl. I am usually generous (sometimes too much) but I despise getting scammed. Who doesn't? The advertised prices are completely false. No one will give you a $20 couch dance, it's at least 40 and hope they don't start in the middle of a song because that's all you'll get. 15 min private starts at $200. If you do go and want a more accurate price scale just double whatever the club advertises for dances at every level and that's IF you negotiate. I wouldn't mind paying more but don't play stupid games about it.
I do have to add that as far as the club itself, the layout is nice and never had any problems with the staff/mgmt/valet/etc. Maybe it can be a great place again if management can reign in the girls. Use that pimp hand now and again.
I'd recommend Palomino if everyone in your group is over 21.
