You can order Shake Shack for pickup on your mobile device
How did I not know this? I've been living in the stone ages waiting on my local Shake Shack line. With the Shake Shack mobile app you can order off the entire Shake Shack menu and pickup at your own leisure. It's one of the pleasant ordering experiences I love about Sweetgreen, but now with less salad -- at my favorite burger joint! Will try this out soon and report back.
