The restaurant we booked TWO MONTHS AGO backed out on us and all the places we like are now booked. So, it falls to us having it at our house (close to the Arboretum, if that makes a difference). It'll hopefully be the second Saturday in December with 20-25 adults (no kids).
I've given serious thought to doing it myself and doing either lasagna or fajitas (both no stress at all), but my partner is stressed about leaving a mess till morning.
If I'm going caterer, though, I'd want something nicer. You know, appetizers, a nice dinner and dessert WITH set up and clean up after. Party should start around 6 and end around 9:30 or 10.
