OMG  OMG OMG!   that sounds  AWESOME! 
I'll definately be doing these this summer. 
The only way I don't like mussels is over cooked.  I do prefer mussels over  steamers/littlenecks, but that really is  splitting hairs. 
I don't have a recipe for  Mussels.  I just  do them quickly in some  preparation that calls for butter, white wine, lemon, garlic, onion.... and if there are herbs and extras,  its all good.  Steamers/littlenecks  I don't  gild  as a rule. Broth and butter are  all I NEED.
