Absolutely! Me and DCs had a Chinese takeaway last Christmas as DH was working and I didn't want the faff of cooking. Would do it again. Delivered fresh from our local restaurant which is open in the day.
We've done that exact same thing before it was fabulous! We had 4 under 5.5yrs so wanted to spend Christmas Day with them rather than cooking. We ordered it the night before, cooled it down and refrigerated it all. Reheated in the oven for lunch, bliss! Absolutely worth doing
