Lots of good ideas above. As a fellow Midwesterner, who's also familiar with South Bend (according to your profile, correct?), I think you have a good menu that would be considered more upscale/fancy vs. casual. Looks like you're balancing that by serving buffet style. We did something similar about 2 years ago. The two big differences were shrimp cocktail (a big hit) and a veggie tray (nearly untouched).

We knew, however, that we had no vegetarians. I don't think people expect you to know and cater to their vegetarianism. Often they'll eat a bit before going to a party. But a veggie tray is a safe and affordable option to give them something to munch on with a drink.

Also a note on the bar. It looks pretty good. We had an event with about 75 people this summer, and bought two bottles of gin. Literally one gin drink was poured all night...and it was mine. So if you're not a gin drinker, keep that in mind. Consider if you want a digestif of some sort. Or maybe don't put it on the bar, but bring it out later in the evening. If nothing else it's a good sign you're wrapping up and want people to go home .

BTW, your salmon and whitefish dishes made me really hungry. We just ordered 6 lbs of smoked salmon/whitefish/trout from Charlie's in Door County and I'm hoping it arrives soon!
