It can vary so much. We've been around that time and walked right in, the restaurant was half full. I mentioned to our server that they weren't as busy as I thought they would be this time of day. She looked at me odd and said something like they were pretty busy, there was a 45 minute wait. We were at the counter with our backs to everyone. During that time (20 minutes max) the place had totally filled up and you could see outside there were a bunch of people waiting. So we just got lucky with timing. 20 minutes later we could have been in for a 45 minute wait.
