I'm hosting a casual buffet-style potluck tomorrow for 7 people.

We've got guests on board who are bringing an appetizer, a salad and a dessert, and I'm taking care of the entrees. I plan to serve roasted pork loin, but there is also a pescatarian in the group, so I'd like to offer a seafood dish as well.

We are members of a fish share and this week's catch was flounder. Is that possible for a potluck buffet? Normally I try to serve fish as soon as it's finished cooking, but that wouldn't be possible in this case.

Any thoughts? Should I just stick to shrimp or crab and save the flounder for another day?
