Napoli is a known good thing on this board -- people talk about the lard bread from time to time etc.
I just want to reassert how fantastic it is. Personally I prefer the "flour bread" -- the $1.35 baguette looking thing on the left if you're facing the counter -- but really you can't go wrong. Especially when you get a warm loaf, which come out of the oven 3-4 times daily.
Maybe it's not *quite* worth traveling for -- unless you're coming to get mozzarella from Georgia across the street, which is worth traveling for (particularly on Saturday morning when you can also get fresh hot roast beef) and not long for this world.
But if you live in the area there's really no reason to buy bread anywhere else.
(They still do great business, so it's not like they particularly need more customers at the moment. I just think it's great and shudder when people buy bread at the Key Food, or even when people by the day-old baguettes at Bedford Cheese shop [one option which yes I know Napoli supplies].)
