A Side-by-Side Drive Thru, also known as a "Y" or "Merge" drive thru,
is comprised of two lanes of ordering traffic side-by-side, each with its
own ordering point, but merges into a single lane with one or two drive

A Dual Drive Thru is comprised of two completely separate drive thru
systems, each with its own lane, usually on opposite sides of the

a combination of different drive thru types.
