Renaissance for sure. If you can get in, Great. If it is booked, don't sweat it. Also, don't sweat saying the wrong thing in front of anyone, unless you are a moron. I would assume you are motivated, qualified, and damn happy to be showing up for an interview, so what could you say to upset anyone? You might overhear some guy who is taking his off probation check at the other table in the bar/restaurant. Ask him/her about the LOI and the interview, at least in general terms. Odds are 100 to 1 they had a positive experience and so will help put you at ease. Oh yeah, offer to buy him/her a beer. Probably won't accept, but can't hurt. 2 beer limit the night prior for sure, 1 even better. Good luck.
