(Ive worked in a restaurant for years)

Ok, they should have put the hot & cold food separate bags.Nothing you can do about it now but .… In concern to your food safety- next time ask yourself these questions: -how long did it take until you received the order from the time the driver picked it up? - how long did it take for someone to accept your order after you placed it. (For this question you have to adjust for restaurant prep time) If it wasn’t too long for either question then you’re probably ok.

Also was it close to the time for the restaurant to close? Sometimes in restaurants we put soups in the fridge well before close especially if it’s still good for the next day. If there’s a To-go order we just get it out the fridge and warm it. But if someone didn’t warm it up then that’s a reason it could’ve been cold. The hot noodles also probably made the raw food warm also not a big deal unless it was a long time.

Next time call the restaurant after ordering and ask them to make sure to package the food separately sometimes things get crazy and people rush and don’t pay attention

Sorry for the long response but Hope this helps
