Even though it’ll be a balmy 50 and sunny, I’m assuming we’re eating inside at Nite Owl, rather than a la trunk? 
For those that don’t know, if you go around the corner from the take-away order windows, there is a door that leads to an old-fashioned malt shoppe straight outta Happy Days. Small, but booths and tables should be able to accommodate us all, especially if we are there right when it opens at 11.
