You can wait less if you're willing to eat later in the evening; like, stand in line for half an hour and get a table for one of their last seatings of the night, and then go hang out somewhere else and come back. It also varies depending on the day of the week (obviously weekends are more popular so it's easier to get a walk-in table in the middle of the week).
Arrive at least an hour before they open if you don't have reservation
