From all that I've read, it seems that this scenario would work-a party makes ADRs at a TS restuarant. At the time of the ADR, they show up and ask for the meal order "to go", maybe they're too tired to sit in a restuarant, or whatever the reason. Anyone know of a time when this DIDN'T work? However, to walk up to a TS restuarant without an ADR and get a meal to go, I'm not sure that'll work.
