First, let me say that the food here is really good. The burgers are fresh and delicious and their fries are crinkled. There is nothing better in the whole world than crinkle fries! The house made lemonade is the perfect combo of tart and sweet. My 2 star review is because the Shake Shack app leaves MUCH to be desired. If you're not a fan of waiting in ridiculously long lines the app is a must. However, out of the 4 times I've tried to use it I've only successfully been able to order once. Every other time, after I've done all the steps of choosing a pickup time, choosing my items, and putting in my credit card info it errors out right at the end when I hit the submit order button. An error message pops up that says "Ruh Roh! There was a problem processing your order. Please try again later!" The Scooby Doo expression is super irritating after you've "tried again later" several times. Like I said I was only successful ordering ONCE out of 4 separate attempts on different days. That's a piss poor ratio.
