I've used this method many, many times in the past when preparing chicken breasts and it makes all the difference in the world, albeit on a much smaller scale.
Perhaps this is a way DoorDash is trying to encourage some to reconsider before opting out of tipping the people driving here and there to deliver your order. Or maybe they just want to reward people who offer more compensation to their drivers. Whatever the case, it may be something you want to consider.
I've not tried this place yet, but I've heard from several people it is very, very, VERY good. And unlike many other restaurants for a couple of reasons.
