Roscioli, except for takeout, seemed to me to be strictly for tourists. It’s a deli that they turned into a cramped, uncomfortable restaurant by jamming in a bunch of patio furniture. Their spinoff Emma a block away has an expanded menu in a lovely, comfortable space.
While in that area, stop in at Beppe e i suoi formaggi and get some picnic stuff for the trip north or whatever. They have some great raw-milk French cheese that’s illegal here in the US.
