The secret New Yorkers keep from the tourists is this: Famous Grimaldis Pizzeria is an imposter (it is tourists only in the huge line out front). If you want to eat the real pies of pizza impresario Patsy Grimaldi, you need to go to Julianas next door. Patsy and Carol Grimaldi sold the original a decade ago, but when the new owners moved to a larger place up the block in 2012, they decided to reclaim the first space, with its superb coal oven. So try the real deal: Julianas crusts are thin, with nicely charred edges; its sauce is just sweet enough; and its cheese is always melting on the pies. Tip: The lines here get looong, so if you just want za (they also do excellent salads and pastas), skip the line and head inside to ask for pizza to go. Then picnic in nearby Brooklyn Bridge Park.
