Blindshooter: Not a drive thru - but I have used them often when going on road trips.
I stop at "Cost-Co" and buy a whole roasted Chicken!
Then with my Leatherman tool (which is always on my belt) I slice off the amount I want to eat and get out my miniature Sea Salt salt shaker and dust it a bit and chomp away. Their broasted whole Chicken is very tasty and very fresh! The Cost-Co folks all only allow the whole Chickens to sit (once done cooking!) for two hours then they remove the Chickens to the back room and workers there de-bone and clean the skin off the Chicken and sell it as bagged fresh chiken meat.
WAY cheaper and IMO it is WAY better than the glop at drive thru's.

P.S.: On the way out of the Cost-Co be sure and stop at their snack bar and get a double handful of napkins.
