Hi,
Chinese food, unless it is BBQ, seems to be best eaten soon after it is prepared. I would seek a Chinese food caterer who is closer to your location rather than further. There is one Chinese restaurant that is closer in proximity to you than Chinatown and is at least near to Logan Square:
Friendship Chinese.
Friendship Chinese Restaurant
2830 N Milwaukee
Chicago
773-227-0970
If you are not obligated to a location, I would definitely look into having your banquet in a Chinese restaurant with family style service. Otherwise I would have the food delivered just as you need it for the maximum freshness and taste.
I hope you will report back on what you decide to do and the final outcome.
Regards,
