When to pick serpentine
•
30 to 80 seated guests (beyond that, flow gets hard)
•
Plated or family-style service, not a distant buffet
•
Long venue (barn, tent) rather than a square room
•
Family vibe: you want one visual « block »
Pitfalls
Tall centerpieces blocking sightlines on curves.
Guests on the outer horseshoe: they only see backs.
Service: caterer must sign off on plate rotation direction.
