Finding a great classic drive-thru on Route 66 wouldn't be a surprise -- but in the middle of busy Broadway? Still, the traffic on this artery can make you feel like you're on an interminable road trip without even leaving the city limits, so pull over and treat yourself. Griff's serves up burgers wrapped in waxed paper, along with fries and shakes at prices better suited to a time when the cost of gas didn't make just idling in the drive-thru lane the most expensive part of dinner.
