Stumbled on this place today. Around since 1979.
They bake their own very nice panini rolls and foccacia.
Their sandwiches (Parma, Melanzane, Tonno, Pollo, Caprese) look out of this world.
They also have very nice looking pasta take out.
They also have a small selection of sweets.
I just tried the bread and it was excellent and very authentic. They have signs all over indicating that they do not generally sell the bread. They save it for the sandwiches.
