Maria 300 was the most popular restaurant in Little Italy from 1934 until 1974, when Maria Allori, the owner died. Henry Louis Mencken ate here along with Gene Autry, Rocky Marciano and Dean Martin.
Here is a recipe from http://www.chowhound.com/topics/471992 for their garlic bread
Two loaves of seeded Italian bread
3/4 pound of unsalted Irish butter (or unsalted Vermont butter)
one head of garlic, minced (yes, a HEAD of garlic, minced. A LARGE head of garlic!)
crushed hot pepper flakes
Slice the bread with a bread knife approximately one inch thick
Coat each slice with a heavy layer of the garlic mixed/blended well with the softened butter-there may be a bit more than a tablespoon for each slice; perhaps two tblsp. It is easiest to let the butter soften to room temperature for an hour or so before blending it with the garlic.
Grate fresh Reggiano over each slice; coat the slices with the Reggiano for a full layer of cheese on each.
Sprinkle caraway seeds over this
Sprinkle crushed basil over this
Sprinkle a few hot pepper flakes over this
Bake at 350 degrees for approximately ten minutes until the bread is crusty and the interior of the slices are soft from the melted garlic butter. Serve HOT.”
