Don't ask me why but Cleveland is the Clambake capitol of the world.
We don't eat clams in months that don't have r's in them.
Clambake season starts in September (obviously)
Unless you live on the beach we do them in steamers with chicken or steak, sweet potatoes and corn on the cob. Serve chowder and you have yourself a bake.
Around here, we can buy entire bakes, rent the steamers and be done with it.
We have ours catered, cost is about $20 a head.
By the way, where would you get rockweed in Pittsburgh.
Loree, pm me if you have any questions, or need help.
