My wife and I have been to the red rooster and had a good time we will only be in Vegas a few days on a sat sun and monday and didnt want to waste our sat night. We have never been to the rooster on a Sat. Dont know if it will be too busy to have fun.
I went to red rooster on a date on a Wednesday and it wasn't very busy and no action was really happening. Maybe on the weekends it's better though! I heard good about the green room
I find that RR and Green Door is more relaxed in the couples area. Not sure if Couples Oasis is still around but a good option for real couples. Purrfect has used different public places around town (rooftop @ Rio; Fizz @ Caesars) and currently hang at Rumor across from Hard Rock.
