While it seems most establishments with drive-thru windows are in agreement that bicycles are forbidden, and refused service, Washington-based restaurant Burgerville is leading the way to change that.  All 39 of their stores now allow cyclists in their drive up lanes, giving free smoothies to the first batch earlier this month.

The intention of our Bike Friendly Service program is to create a consistent policy and experience for our guests in the drive thru.  To support this program, a cross-functional team, including members from Hawthorne Burgerville and community members from the Bicycle Transportation Alliance, have designed and are beginning the implementation of the first phase of the program.
