I'll add my experience just as an FYI. I have gone twice on a weeknight recently but on the later side (7:45-8pm). Both times I was told that the wait would be 45 minutes. Both times I went over to WC Harlan to have a drink while I waited. Both times Clavel actually called me 10-15 minutes later and I had to scramble to pay my tab for the drink and get back over to Clavel. If you go at this time (around 8) you can just put your name in and it's only about a 10-15 minute wait.
