Recomendation for romantic place?
In Cobble Hill/Carroll Gardens?
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.
If you're willing to include Park Slope in the mix, I'd suggest Convivium (especially the wine cellar).
