Works perfectly at Georgia Tech!
I use the app at Georgia Tech, where the lines can get horrifically long at Chikfila and Subway during lunchtime (the Subway line I have measured as 35 minutes long during noon.) With this app, I ordered and got my sub 6 minutes later, after a class and immediately when I walked up to the counter! Not only that, I got $1 off my sub for using the app. I highly recommend the app, at least for GT students.
