My parents met with the caterer today. Mom says she is "very nice."
More importantly (maybe) -- it turns out we can have a crepe station. And an Italian soda display. And blood orange juice!!!! And pretty much everything else we could think of. Yay!
Basic brunch starts at $25/person, then goes up with add ons (generally around $8/person per food station). As far as I know, that doesn't include renting linens and all of that nonsense. Who knows what it will end up being. The caterer says she'll send a price breakdown in the next couple days.
All I can say is ... crepes! My dream will come true.
