They don't mention that Jony walks from Pac Heights, and instead of going directly to North Beach, he must have climbed to the top of Coit Tower's hill to access that particular staircase down to Jackson Square, then has to walk the long way around Telegraph Hill right past the cafe to climb uphill into Chinatown for another walking shot, then backtracks to the cafe. Another small irony is Jony was heading toward Lombard at the start, so if he walked a straight line to Coit, he would have walked right past Sam's driveway.
