Poor design and tested app – Burger 21 Patty Perks Review

We were planing a visit to Burger 21 so I decided to see if I could use their app to skip the line. But I could not even reach the menu with out been asking to login for the 5th time. Plus received a lot of 404 errors. I hope the young company gets their act together as the burgers are good but the overall management needs some structure.
