Recomendation for romantic place?
Lucali's is really romantic. Bring a bottle of wine and enjoy your pizza by candelight while listening to some Caruso.
Alma's rooftop on a warm evening is also quite romantic and the view is stunning.
Bocca Lupo is also very nice later in the evening, when the crowds have died down. Grab a window seat for privacy.
And finally, I'd add Frankie's to the mix. The exposed brick, the big old fashioned bar and the general vibe is pretty romantic.
