I was at Ruth's Chris last night, the wait was 45 minutes long without a reservation, luckily there was a couple of spots at the bar counter so we were able to sit down without any hassle.  Little incidents like this really make the wine and food extra tasty.  I don't always go out on Friday nights, but sometimes it's just nice to sit down and let the wine relax you and listen to the tinkling noise of ice hitting the glasses and people laughing and talking around you.
