Montclair NJ area - Thanksgiving Catering
I used to live in Cedar Grove and Mardi Gras http://www.mardigrasfoods.com/ was on the way home from work. It's about 1/3 mile from Montclair on Bloomfield Avenue. I often had them prepare my dinner parties. They have pre-set menu choices for holidays. You order what you like and pick up the food on the day of the event. Their baked goods and entrees are really good.
