Fast casual chains drive by drive-through concept

|By:, SA News Editor

Don't look for a lot of fast-casual chains to move toward offering drive-thru windows as a growth driver, according to Restaurant Finance Monitor.

Panera Bread (PNRA +0.7%) has dabbled with the concept, while it sometimes gets thrown into discussion on the growth matrix of vibrant chains such as Chipotle (CMG +0.2%) and Noodles (NDLS +0.6%).

Inside the numbers: Though incremental sales are picked up from on-the-go diners, unit economics dictate there is more value in developing normal store units than investing in large build-outs or retrofits. Just ask Subway.
