well... i just got married in august.. we did buffet style. but we did it more summery..
we did grilled chicken sliced and marinated with ceasar dressing...ceasar salad. We also had a nice fruit salad (we did nectarines, strawberries, blueberries and raspberries), my family's yummy Italian pasta salad (I'd be willing to share) All the sides for the salad (onions, parm. chz, dressing, croutons) We also had rolls and butter for those who wanted them..
Everybody enjoyed it! It was really good, but nice and cheap. We're still getting compliments.. There were a lot of people who weren't sure about it (i.e. my husband's mom) but we did it anyway, and everyone loved it!
that's just my ideas
oh and this served over 100 people, and it can be scaled down or up easily...
