I'm a fan for going early in the evening when it's not jam packed with people and you can get a seat on the patio, snuggle with your sweetie and enjoy the gorgeous view of the strip. Later it's just tooooooooo crowded! It used to be members only club back in the day and it was much better then.
If you are new to Vegas this is a great place to grab a drink and enjoy the view! If you like to people watch it can definitely get interesting. You never really know what kind of crowd will be there.
