The muffuletta is my favorite sandwich, by far. And for me the gold standard has always been Central Grocery. I’ve had countless muffulettas from other locations, but to me, the original has always been the best.
However, I have a new favorite muffuletta (as of two weeks ago). The one from Cochon Butcher is smaller (and cheaper), but it’s full of meat (which is homemade) and there’s a thin layer of olive salad on both sides of the bread.
I still love Central’s sandwich, but Butcher’s is slightly better in my book.
