This is slightly off topic - I'm thinking about the food served in
restaurants. Take Chilli's or T.G.I.Friday for example (a chain, but
not "fast food"). How is the food prepared there? Let's say I order
a grilled chicken sandwich. I assume the cook pulls a portioned
chicken breast out of the freezer. Maybe its already cooked, or even
partially cooked so it just gets heated? Was the bun fresh (never
frozen)? I have to assume the lettuce and tomato that came on it were
fresh, right? I would guess if you order a plain salad that
everything in it is fresh (croutons, bacon bits notwithstanding). How
many deliveries would a chain restaurant get in a week in order to
continually have all the fresh ingredients they need?

Now think about the local Chinese restaurant. Surely some of their
seafood and meat offerings have to come to them frozen. After all, if
I order sesame chicken (essentially chicken nuggets fried then covered
in a nice sesame sauce), it had to be frozen until I ordered it,
right?

Procedurally, does a chain or local restaurant thaw out all the frozen
items it thinks it will need in a given day, or just thaw them as
needed?

Thanks for any info....
