Don't have many spare cool boxes unfortunately and I'll need to put soft drinks in some of those.
Just thought popping the bottles in a freezer for an hour or two would be an easy option as there's plenty of space in there / space can easily be freed up.
Apparently, never recommended according to my in-house french chef! We use an external insulated box packed with ice when we have these kind of days.
We do have a drinks fridge though.
