Cantina de San Angel actually eliminated the combo platter in a menu change about a year before it closed.
Takeout from a TS has proven difficult with
DDP - there was a restaurant (I thought it was Beaches & Cream but now I think it might have been Olivia's) that accepted takeout meal orders before DDP and stopped afterward because guests complained that they expected to use CS credits for takeout food, not TS credits. If the pizzeria is on the dining plan and doesn't intend to serve slices, there won't be any good way for them to accept CS credits. Can't see them accepting CS credits for a whole pizza for carryout, considering the kind of money they will likely charge for a pizza at table service.
