A lot of variables--the biggest usually which local schools are out the next day as we head into Fall Break season--but in the past few years Sunday just as crowded as any other night. Friday is usually just moderately crowded, and in fact pretty quiet until around 8:30 (free parking kicks in at 8:00, surprising number of people wait for that). Wednesday and Thursday are variable--again, school schedules play a huge role, but it seems somewhat random as well. Can be slow, can be slammed, tho usually clear out a bit after 11.
