It troubles me since this is a subject that is lovingly obsessed over on other city boards. "The Very Best Meatball Sandwich, located at Restaurant X ..." Click on these postings, and you'll read some excellent debates (re: spices, sauce, cheeses, bread toasting ...). On the SF board, have I been searching under the wrong keywords? They may go by a different name--hoagies or grinders? In any case, my own feeble search is yielding only two leads, Rocco's and some pizza place on El Camino, so I hope I can get some more recommendations from savvy locals. Thanks. Someday I too will be able to proudly post a description of "My Favorite Meatball Sandwich".
