If you are going to take it to go, i highly recommend you pre-order it online, which to go orders are online only, no over the phone orders anymore. Once you arrive to the restaurant, there is a separate shorter line for online orders. I used the 10% off Yelp discount. Even thought you pay for it online, they said the charge won't go thru until midnight, so its ok to put in your card number and then present your discount until you arrive.
My favorite part about the burger is the bun, everything else is good too but not as great as the bun. You have to try the Smash Fries, they are their fries tossed in olive oil and rosemary.
