Team Taco uses cardboard packaging. Thai Express uses plastic, but they're the nicer kind that's reusable. Boskys uses sustainable packaging.

I'm at a loss on Chinese restaurants.... All the standard places I'm aware of use styrofoam clamshells. Except, like the family pack (individual entrees/sides) at Panda Express with the classic Chinese boxes.

Thinking of Hong Kong Inn, Cashew Station, Bao Bao, Cashew Chef, and Lucy's.

I haven't had China King in years, but, at least the one in Republic, used plastic containers.
