In and out hands down. Wish we had them on the east coast. For this coast I'd say Shake shack if I'm truly craving a fast food type of burger. Sonic's double quarter pounder is great for the price but there aren't any close in my city so mainly a quick go to when traveling. Chili's has yet to disappoint me if you've got an extra 10 minutes to wait or pre-order while on your way to pickup, so wouldn't conser it fast food.
